Finger painting. In Sevilla, I watched a street demonstration of painting with oil on glass using only the fingers. The lady artist was so skilled that she could produce the entire image in 1-2 minutes. She's selling them at E 1.50 the piece. * I didn't buy any, but I thought it was fair to give her 1 Euro for the demonstration and for encouraging her :) Andalucia, (Andalusia) Spain
