Yeah... I saw that earlier too. This MultiCortex thing doesn't look to be anything ground breaking to me. Many others working on it, including all the big guys and likely much further ahead.
The first OTC company that I ever encountered announced a reasonably priced desktop PC that had (IIRC) something like 12 screens connected to it. This was probably 25+ years ago when having 2 screens on a PC required a Matrox video card that cost nearly $ 1,000. The product and the company was so clearly a scam. They kept releasing "photos" of the new computer with more and more screens connected. At some point I think it reached 20 or so. They set a release date. Just prior to that date their web site disappeared and the company was never hard of again.
I wish I could remember the name of the company so I could check archive.org but my memory fails me.
