It doesn't matter when you grew up, you should have watched the Back to the Future trilogy by now (and loved it). A chance to get your hands on something pretty exclusive just emerged, as a one-of-a-kind pinball and arcade game tied to the franchise is being auctioned off over at Ebay.
You will however need to cough up some serious money, because the bidding is currently at $4,238.88 with a handful of days remaining. All the proceeds will be donated to the Michael J. Fox Foundation for Parkinson's Research, so at least your money will go towards a great cause.
