Checkmate!

Lightmen playing chess. Prize to whomever can say which game the position is from. Hint: it's pretty famous. The prize is only bragging rights unfortunately... :)

 

Extra bonus bragging rights if you can name the artist and picture on the wall!

 

I'm sure if I like how this turned out, but I thought I'd upload it anyway as I went to the trouble of setting it up.
