What Wiimote attachments would you like to see?
(I searched for forums like this and couldn't find any so sorry if this has already been posted before)
I think a little keyboard, like the little keyboards that are on smartphones and stuff, that could somehow easily be used would be cool, so entering text and other things isn't so tedious. You could attach it to one side maybe and then just turn the controller to the side and enter text...
And also maybe a little pad that would act as the sensor bar and then a Wiimote-like pen to use with that... This could be used with the photo channel.
