Step 3Rear projection screen
The screen needs to be just the right amount of see through-ness! If it is not transparent enough, the image won't be seen and the infra red LED won't be visible to the wiimote's camera. If it's too transparent then the projector will be blinding and the image washed out. (Though see the last page for ways of mitigating this).
I used lycra, which is stretchy so I can stretch it to make it more transparent. At the moment I hold it on with thumb tacks, but I'm graduating to velcro when I get access to a sewing machine.
I made a wooden frame with the help of a workshop and a carpenter (thanks Lou!) I needed it to collapse so I could transport it on my bike. If you're making one for a fixed venue then it will be easier to make. Just make it at a 4:3 aspect ratio, and stiff enough to stay upright.
I've found people tend to push on the screen material a fair bit so it needs to be a bit rugged.
