I met an artist, Danielle, at the 7th St block party. She paints on helmets :)

Each helmet is hand-painted by Danielle Baskin in acrylics and sealed in a UV-protected oil-based varnish that repels water and prevents chipping.  Not very eco.. but biking is and it make biking more fun and that is moving toward clean water air and soil.  So I pass her for a succession maker.
