Has anyone used/seen a multi-panel screen set-up before?

[Hhal]

I was scrolling through eBay for good deals on discs, as has become way too regular for me, and saw some 3D discs that tempted me, so I went to look at secondhand 3D TVs on the site. When I have done that in the past, I only have found things that won't ship and are too far to pick up, no matter how good the price was. Today, however, I also saw this item with a starting bid of $40,000!

I felt the need to share this. I don't know what to say other than to ask:

(a) Do you think this is a legit seller? Not that I could ever buy this.
(b) Is this as good as a setup as his item description makes it out (to an amateur home theater enthusiast like me)?
(c) With a multi-panel screen set, can you get distracted by the lines between the connecting screens? How does that work?
