I'm glad to hear you enjoyed my etch-a-sketh piece. People always ask how long it took me-- it wasn't as long as I would have thought, around 4-5 hours I think and just one take. I did the Mona Lisa a long time ago during a slow day at a retail job, which is where the idea came from.
I intended to make the piece into a series and have some new images waiting in the wings. Stay tuned!
