The Gray Area Foundation For the Arts

How was this place in downtown SF for 6 months without me knowing about it?? http://www.gaffta.org/ They basically focus on exactly the kind of art I like to create most -- digital, visualization-oriented, interactive art. Their Youtube intro is great too.

Useless warnings

I had been wondering about those "Prop 65 lead causes cancer blah blah" warnings in the balsamic vinegar section of the supermarkets. They put those signs everywhere now since more or less everything contains some amount of some carcinogen and lawyers are in plentiful supply. This of course makes signs warning you of significant cancer risk totally useless as they hide amidst the magical protective legal incantations that shelter balsamic vinegar manufacturers and others from frivolous suits. How about three colors of sign -- mild, moderate, and serious cancer risk? We have maximum daily exposure levels and can get some sense of the exposure level from a product in typical use scenarios, so we could set some thresholds for the categories. As for balsamic vinegar:

All balsamic and red wine vinegars contain naturally occurring lead. Lead is naturally absorbed by all things that grow in the ground, including the grapes used to make vinegar. Most balsamic and red wine vinegars have lead levels equal to or less than 34 parts per million. An average person would need to consume 1 to 2 cups of balsamic or red wine vinegar per day to reach the Proposition 65 lead level minimum threshold, which includes a 1000-fold safety margin.
