unusual uses for technology - no.1

I've got a mouth ulcer (which may explain why I'm not my usual happy go lucky self this morning) so went to the chemist for something to treat it. The problem is there are no mirrors in the office and I need to apply the treatment directly to the ulcer. The solution is to use the web cam on my MacBook with the preview feature on iChat. Fantastic. Bet you can't do that on a Dell.
