I’m not sure how ergonomic the MUS2 Mouse is but it certainly looks a bit different to the usual multi button keyboard companion.

The mouse is shaped like a typical screen cursor, so to keep things simple you move the cursor on the desk to move the cursor on the screen, the mouse even morphs into an hour glass when windows crashes* (* - that may of been a slight exaggeration).

Looks cool to me and for £50 it should. You can get the MUS2 mouse from Boys Stuff (also compatible with girly hands).
