I was asked to do a painting for a wedding invite based on the famous pinup artists like Rockwell and Elvgren. It was to include the bride's own dogs and be a bit saucy. I used Fractal Design's Painter X along with a huge Wacom Digitiser to get the feel of oil paint. It's brilliant. You can work wet into wet, use glazes and wipe areas off, just like the real thing. Without the cost and the mess. Cool!
