The Cat-Lapse Photography Project: Moar weekend (for those who care, (not cats)).
I double-dog dare you to photograph a day in the life of your cat. That means once per hour for 24 hours, you take a picture of your cat.
Now you can't disturb or inconvenience the cat in any way. You must find it, unobtrusively snap your shot and go back to bed or whatever you were doing.
You worry that this will produce only a boring montage... a cat sleeping... more cat sleeping.... yet again cat sleeping. But people do time-lapse photography of plants, for God's sake, so a cat's 24 hours must be a little better than that.
At least I'd look at all 24 pictures.
