It's a sad thing. I enjoy art made by passionate people. Be it religious art or album art. The artist love of what they are trying to honor comes through with a subtle strength that is hard to find in your average day.
I hope the art form sticks around and even strengthens as more iPod players get screens and the new digital medium, e-paper.
There is still one other venue for passionate art... Art cars, hot rods, and customs.
