Over in the Sony Vegas forum, they were discussing various time lapse stuff and one person had some information that may be useful to the folks here. Nikon has their Camera control software that runs on a laptop etc which I was aware of, but for the Canon folks, here was the comment that sounded interesting ...
However, almost any Canon Powershot camera can be modified for time-lapse. Google "CHDK" and you'll find..... a google of articles on the Canon Hack Development Kit, which includes a time-lapse hack.
(this was the thread over in the Sony Vegas forums - I loved the chapel one somebody linked in as well as the icicle growing outside one guys window:
