At an old job in 2003, my office mate quit and left these amazing hand rests which I began to use. I loved them so much that when they broke in 2006 I actually super glued them back together. At that time I couldn't find anyone selling them on the web. Now, they've broken again and it looks like I can get them here: http://www.ausconn.com/ - see the "Comfort glide" area - third picture from the top left (I know, amazing website). Apparently they're made in Australia. Seriously, these things are amazing.
