That stuff reminds me of the bicycle industry; every year someone would show up at the big trade show with something that'll change the world...that been done before five years ago and failed...they always ended up in the same area of the show (sideshow?) and they'd always die a slow or fast death depending on their funding and blindness...Ebow is still around though and I saw a show with Peter Frampton using one just yesterday...
I saw 2010 when it came out and forget almost everything about it, I should watch the two movies again...I miss Arthur C Clarke, and Stanley Kubrick...Tony
