I found this link to instructions on making a rear projection screen for classroom use.

Has anyone tried this and succeeded? What material did you use?

Tell all please?

Hi,
Here's a screen made from the cheap disposable table cloths. They are white and $2 each. I used 3 for the play. You can buy them from the "cheap" warehouse stores. They were taped and hung from the rafters of the room. and were taped to a wooden beam which lay on the floor. The data projector was placed about 3 meters behind this screen and provided all the backdrops and scenes for the play which was a humourous version of Cinderella. In the dark, it gave a huge, very clear image. Over 3 metres wide by 2 metres high. The best part, no shadow was being cast on the image. The children performed in front of this. Looked very impressive. You do need to flip / mirror the image on the data projector settings so that text is able to be read. You wouldn't want it this big for normal classroom use though.

If one tablecloth was stretched across a light wooden frame it should work. As I took this photo before the concept of the wiimote (back in 2006) I haven't tested if the IR Pen can be detected through the plastic. If not, the wiimote would need to be placed behind or to the side of the user.

Good luck,
 Joe.

   
I'm using the rear projection of the room features table. Traditional chalk board behind the projector from the rear window. Thus, the two tables in turn use the teaching period.
