ps2 motion controll?

look at what i found on the eb games web site. http://www.ebgames.com/product.asp?product%5Fid=802593

now how would this work for a game like area 51?

and does it only work with some games or what? how does it work?

I'll pass. People don't want motion controls, but innovative gameplay, which is the purpose of the Wii.
