Promethean ActivExpression - Alternate Uses

[ChrisERoots]

Like many of you, I have many unused ActivExpression Units in the Server Room. I was wondering if anybody cleverer than me had come up with some alternative uses for these devices. The only thing i'll end up doing with them is sending them for recycling. I'd love it if someone found out how to use them as a Powerpoint Clicker or something...
