Here's an idea seeing a number of people have a Dolly pin waiting in the wings.
Somebody make a scan of a Dolly playfield accurately plotting where all the holes and inserts are located. Then post it up here for all the amature and professional artist on the forum to take a whack at creating their own retheme.
The artist then post a thumbnail version of their work for all to see. If a Dolly pin owner likes what they see, they contact the artist in question for the "print size" version of the file so the can take it to a printer, like what Betelgeuse did with his "GhostBusters".
I think this is a neat idea, but have no idea how it would workout in real life.
Some wordy disclaimer would go here basically saying that any exchange of money, goods or services (if any) would be between the artist and the end user, this website and it affiliates would not be involved.
