I was able to see the development card in person at VCF Midwest last year; it's a very neat project! The version he had at VCFMW was in a transparent plastic case[1], which looks even better than the IBM-inspired design of the one on this page.

Edit - I found this video on his YouTube channel with more info (with the latest version of the card): https://www.youtube.com/watch?v=e-04EoGlayY
