Can you make or buy LED "peg" boards like the old Litebright Toys?

I want to be able to customize the size. Put a picture over the top of the peg board. Have it be back lit and be able to "plug in" various colored LED lights anywhere within the board and have them light up. I would also like to have the boards in different electrical currents 240, 120 etc.

Try "Peggy 2" from EvilMadScience

I bet you could mod this pretty easily....
