My dad is a patent and copyright lawyer, so I've always had a real fascination with inventions. He turned me onto the quick-and-dirty patent confirmation tool known as Google Patent. It's pretty self-explanatory. I was thinking that there must be some pretty rad PINBALL inventions documented there, and then I found THIS:
Patent for Linkable Pinball Machine
!!?!?!?!?? Designed by George Gomez?! Connect multiple pinball machine together for cooperative gameplay!?! Why have I NEVER heard of this!?! Can you even imagine how amazingly cool that would be!? Discuss!!
