i saw that this morning and was wondering if that would become your next project for DNA. :-)
It's a great setup, but I'm far too distracted by the immense borders of the monitors and how they break up the image to be able to enjoy it much.
A bunch of old laptop screens would look much better, and would be fairly cheap to obtain.
Even some old low-res tubes from old videogames would work better than this, since you just have the tube itself with no enclosure around it, and it already comes mounted in a bracket. You could probably get a sweet deal (especially in these trying times) on old tubes from one of those places that sells reconditioned coin-ops for ridiculous prices.
