Hi all,
I designed this holder for the Mayflash Dolphinbar today (so I can use a wii remote to control my pointer location) and I thought that other people might appreciate it.

It has worked very nicely for me so far, and holds itself onto the laptop with friction alone.
DISCLAIMER: I am not responsible for any broken screens resulting from the use of wii remotes, regardless of if you are wearing the wii wrist strap or not.
Edit to add: You should also probably remove the holder from the laptop before shutting the lid.
