Welcome,
Just starting out on my works with multitouch.  I’m looking at a few months of development on making the box, then quite a while coding on it.  So far I picked up the wrong thickness Acrylic from Home Depot, but no worries!! I’ll be going back with my reciept to get the right one sometime next week.  Also, I’m saving up money to get the rest of my components together.
I’ll be keeping this updated as things progress.
