The wonderful folks at Zeum, a children's museum in San Francisco, have put together a really nice installation of Glowdoodle. During my visit to the Exploratorium this summer I had a chance to visit and check it out. In a big, dim circular space, they've got two kiosks with tethered light-brushes, and large projections on the walls. The kids seem to love it! They can generate hundreds of glowdoodles in a day, which get collected here.
