cordless screwdriver shaped wiimote   (+4)  [vote for, against]

Quite simply, to switch to gun mode, you move the head of this 'wiimote' down so its at an L shape.

To switch back to normal mode, just straighten it out.

Maybe you can even motorize the hinge, so at a button (or a trigger pull, you can switch immediately to gun mode)

I'm disappointed - I thought this would be "Wii DIY" - a game in which you have to do virtual DIY, gaining points for speed and quality ("Also available! - Wii IKEA - assemble virtual flatpack furniture!").

I agree with [hippo]. The progression through the levels could be entertaining, starting with a simple side table, and ending with ferocious L-shaped office suites. As each one is completed, the boxes for the next item are delivered by IKEA men on screen.

I agree with [pocmloc]. For some of the higher levels, laying girders for a skyscraper, or erecting a deep water oil rig. Go on [hippo], post it.

yup definitely like hippos idea. I'll give him a week to make a half bakery post for this. Hippos idea needs to be made :)
