How can I reuse or recycle overhead projector transparencies?

OHP and transparencyFinally on this week’s Recycle This stationery theme, we’ve got this question from Nicole:

Now all my college’s lecture rooms FINALLY let you use powerpoint, I can get rid of all the OHP lecture notes I’ve created over the years. What can I do with them?

According to Wikipedia, most transparencies are sheets of cellulose acetate. The Google results are confusing but I think cellulose acetate can be recycled but I suspect it’s carried out more at a manufacturing level than post-consumer. Anyone know for sure?

What about reuses? I imagine they can be used like old photo negatives to make lampshades and the like – probably would work better for those with photocopied pictures, diagrams or text on rather than hand-written notes. Other ideas?
