Another fascinating day at DIMEA 2008. One of the keynotes, by the Greek artist Michalou(di)s, described sculpting using silica aerogel. It's an incredibly light insulator, but it also has a strange "immaterial" beauty to it, like looking into a cloud. Very cool. I also saw presentations on AI painting, biometric sensing art (right up my alley), and a very cool haptic device that rests on the nail of the finger, but makes the user feel like their touching something in the front.
