Creative submissions have been extended until midnight on Monday for Friday's Slideluck Potshow, a collaborative artistic slideshow presentation and chance for food, drink and conversation sharing at San Francisco's South of Market photography center LeftSpace. Area and international creators alike present thought-provoking creative work around a theme. As this month's theme is “nourishment,” participants are encouraged to bring a dish to pass (suggestions include seven-layer dip, lobster ravioli, barbecue tofu, or Meyer lemon bars—it’ss a foodie group, after all). Photographer Michael Jang will serve as the guest curator for the event, which is a collaboration with the community and food movement organization Eat-Ins.
