Hmm..

The option we are talking about is basically stopping the screensaver and restarting it. I suppose it doesn't have to be just the aquarium. Imagine in a year or so's time, going into your local computer store, and seeing the aquarium running, then it fades out, an advert for the butterfly screensaver appears, and then the butterfly screensaver fades in etc.

Anyway, for home use, I wouldn't want pictures or text between saver re-loads if it could happen quick enough, and on my lowly PII with an 8MB graphics card, it only takes two seconds to start, but your milage may vary.
