That video wasn't too exciting, but one of the related videos seems to fit the bill for the OP's request: http://www.youtube.com/watch?v=3atmWmWCwlw
They may be optical, but if you grab one and look underneath you might still find a ball or two.
You've spent two years on this, and only now getting into the patent? You should be prepared for disappointment. The odds are very high that someone has already patented your exact idea, especially if it's something that you could figure out with no prior RF electronics experience. It's difficult to let go of something that you've put your heart into for so long, but you need to be prepared to do that if you run into problems. Otherwise it could drag you even further down.
Read through some of the tutorials at http://www.fpga4fun.com/ and then head over to the sister site http://www.knjn.com/ to find some FPGA boards. You can get a very good introduction to FPGA concepts for less than $50. The Pluto boards with Altera Cyclone FPGAs are perfect for getting your feet wet.
Maybe quantum computers will be really good at doing this.
