Via Colori is one of my favorite local art festivals.  Artists volunteer to draw on the streets of Houston to raise money for the Center for Hearing and Speech Impaired.  It's a 2-day event held every November.  I was lucky enough to participate the first 3 years.  These are the 4ft x 4ft squares I drew in 2005-2008.
