built in ISight question

I just bought this MacBook Pro and it has built in Isight. It's a work computer, but I used the isight for something I'd rather not have anyone see. I was webchatting in Safari with a Flash or Java based chat client (I don't know which). I was using Private Browsing in Safari, and I've subsequently emptied the browser cache and cleared the history.

Are there any remnants of this (ahem) episode still left on my computer somewhere? Some Isight, flash or java cache I don't know about? Any temp folders?

If this accidentally was discovered during a presentation, I would fall over and die right there. Please alliviate my worry.

Thanks.
