these short pbs “off book” videos are great. this installment in the series is about an art form called glitch art. it’s actually an art form i was already enjoying both as a creator and viewer but i never knew it had a name. the name pretty much discribes what the art is all about: computer generated glitches of still and motion art. don’t get me wrong i don’t think it’s all great work but some of it is amazingly beautiful. check it out.
