It’s cold in NYC. Like, really cold. This Hand Radiator iPhone App turns your iPhone into a hand warmer. This might be the smartest dumb thing I’ve ever seen. Or is it genius. I can’t decide.

The app puts your iPhone on overdrive, using 100% of its processing power. That, as you probably have noticed with some applications, makes the components to overheat, which in turn can warm up your hands

Gorilla Cases are a young enterprise out of Berlin who create rad carbon fiber iPod and iPhone cases. Love it.

I know it seems like iPhone app day here at JS, but this is a neat little post-lunch nap, pre-early happy hour time waster. Longtime reader Pete Anderson (aka Anthropophagy) sent us a note about his new iPhone game called Stay. It’s a simple deal: keep your shapes balanced on the beam while different types of blocks try to knock it off. Trickier than it looks. The full version will be in the iTunes store soon, but for now we have promo codes for the first three readers who comment on their favorite application.

Accessing your favorite social nets on iPhone is currently a less than amazing experience, mainly because of the need to switch between networks, mapping, and contact information (it's enough to make a person frantic). But if the Paris company Never Alone Anymore has its way, the new HiMyTribe app will serve as the location-based people finder of choice. It uses the iPhone and iPod Touch's GPS capabilities to help people manage their groups (or professional and personal “tribes”) and identify people they would want to meet who are in their vicinity. A criteria-based search engine helps you locate people with similar interests, including business travelers, friends of friends, conference goers—even potential dates. (Imagine looking for a well-qualified designer who can meet you for espresso in Zurich on the fly.) There is a “blacklist” option, and exact locations aren't shown until the other user accepts. The free app, which the company describes as the “first truly real-time person to person application for the iPhone,” allows for 20 tribe members globally, or there's a larger network option with a monthly fee.

Last month, the iPhone Brushes app made headlines with The New Yorker cover, which Jorge Colombo finger-painted in less than an hour. New Brushes paintings are added to the Brushes Flickr group daily. So far, one of my top finds has been the work of Jhonen Vasquez whose 90s-era Johnny The Homicidal Maniac comic is a personal favorite. Writes the artist about his latest painting: “As is usually the case, this wee thing was started while waiting to feed on something or other, the way lions draw intricate images while waiting for a gazelle to run by.” The app even has a time-lapse video feature, so you can see the artists in action. Check out Vasquez’ brushwork here. Awesome.

Most people with any sort of artistic impulse don’t reserve their urge to create for when they’re seated in front of a canvas or holding their pen and sketchbook. The drive to innovate can strike at any moment and can be realized by the use of any number of resources. Last but certainly not least on that list of instruments susceptible for giving birth to the mother of invention is the iPhone. Reflect, A new app from our good friend/web design guru Joshua Davis and Sideways Mobile, encourages users to explore their spontaneous leanings by entering the universe of algorithmic art from the safety of their own cellular device. By giving users the power to “produce random, generative pieces, and then view them in a Kaleidoscopic filter” the iPhone turns into it’s own portable art gallery where the walls are covered with the whimsical wonders of your warped imagination…which is sort of a change from your usual, more practical iphone apps; though a whole lot more fun.

FingerBeat is a virtual instrument inspired by retro synthesizers & samplers, designed for creativity & self-expression. A homage to dance music and pop culture, FingerBeat is a classic for absolutely everyone. Only on iPhone & second generation iPod touch. You can check out a video of it here.

Going gaga over the new iPhone? Want to build iPhone applications? Thoughts so.

Wonder what color the desert of Petra is, or that delicious Uni sushi you just had for lunch? Sherwin-Williams just launched ColorSnap, an iPhone application that allows you to snap a photo and get the matching Sherwin-Williams paint color from more than 1,500 in their database. Nice for the designers tool kit. Click here to download from iTunes.   

Update: Speaking of color, check out XOLOR for a color seizure.

For the past year, the urban vinyl community has relied on Face Your Manga for all our avatar needs. But now one of our own has stepped up with an app that renders our likenesses in Kidrobocolor. That would be the awesome Tristan Eaton, whose Thunderdog Studios just released the B-BOT app for iPhone. B-BOT is the closest you will ever get your mug to a Munny. You can create your own B-BOT and also customize your contacts. When you receive a call from them, their B-BOTs will show up on the caller ID (and vice versa).

B-BOT was conceived by Tristan Eaton and Peter Cortez while working together on the 2008 Barack Obama Campaign. It was developed by Greg Elliott, the creator of SynchStep.

It is almost a euphoric moment, a private instance when you let a faint smile appear on your face that nobody else notices. I had one of these moments when I played Last Cannon for the iPhone. It’s rare that a game, especially for the Apple mobile platform, has all the key elements that make up a perfect experience – gameplay, artwork/graphics, music, controls. This hits on all points flawlessly. The story, told through journal entries, is of an post-apocalyptic world. You are the last of your kind after the knurlings rained down and destroyed your world. 

The developer counts Geometry Wars, Dr. Mario and Ikaruga among his inspirations and I can definitely see elements of each in the game. Last Cannon is available now in the iTunes store for just $0.99. Version 1.1 promises to bring online leaderboards which will definitely add another layer to the gameplay.  

As a bonus for the readers of joshspear.com, the creator has given us four download codes to give away. Just leave a comment below on what elements you look for in a good game and we’ll choose four of you at random.

Owning an iPhone isn’t exactly a sign that you march to the beat of a different drummer, but the apps you choose certainly can go a long way towards showing that you slide through life at your own tempo. The new Drum Meister app by Seung yi Lee can help illustrate that tempo, as a realistic drum kit application that allows you to recreate whatever rhythmic pace you feel suits you. Users are provided with an impressive interface where they can arrange their own set and bang the skins to their hearts content and even record and playback their fine percussive work. So whether you’re slamming the cymbals on a solo or slapping around some snare action you’ll never be at a loss to prove that you indeed have got the beat. Drum circles just got a drastic makeover.

Russ Mills is one of our favorite artists, but has a knack for selling out his prints in less than 24 hours. It can be frustrating, but when you actually get your hands on one it’s very satisfying. He's finally released a product that hopefully won't be gone by the time you read this. Partnering with Infectious, he has lent one of his images, “Tilisis,” for you to stick on your gadgets. Only one image is available but in various sizes for Laptop (MAC & PC), iPhone and iPods. Staying constant he has kept his prices low; $30 for a laptop, $15 for iPhone/iPod.

If you've missed out on his previous print releases, this is a sure way to get your hands on a Russ Mills something. In related news, there are talks of a Russ Mills London gallery show very soon. Hopefully, we'll see some more prints soon too. We'll let you know.

With the immense popularity of photo sharing sites such as Flickr and Shutterfly, some might be inclined to say that they need another image sharing URL like they need a hole in their head. Well, once they’re introduced to the new iPhone-centric picture sharing application from Okimok.com, they might want to rethink that stance. This fresh spot for photo exchange allows users to instantly display their current state of being as captured on their pet electronic device and stream it to their friends via a superdeluxe slideshow. So whether you’re across the street or across the sea, you can remain visually apprised of the stunning picturesque whereabouts of your many significant others.

If a vintage suitcase featuring city stickers, a scavenger hunt, and an iPhone 3G were combined, the result would be location-based travel game Gowalla. The recently launched game from Texas-based “digital collectibles” company AlamoFire invites users to collect virtual stamps at the places they visit, hide icons for friends to find, and earn pins of glory, the granddaddy of Gowalla achievements awarded for completed trips. Austintonians and San Franciscans are currently the only app purchasers who can participate in the full experience, but other cities nationwide are being added and partially guided by the recommendations of user-added hot spots. Who doesn’t want to be rewarded for visiting extraordinary and everyday places with phone in hand?
