This is one of the coolest techie gift ideas I've seen in a while. It's a wireless PC remote control with trackball and 18 programmable keys (pic), usable up to a 25 foot range.
Not sure how useful this would be at home (check your email from across the room maybe? :)) but it looks like it would be great for business presentations and whatnot.
Anyway, it's only $10 and looks like a good product so I figured it was worth sharing with the SitePoint community.
