Picture scavenger hunt

My son got a digital kid camera for xmas this past year. When I am trying to make dinner or fold laundry etc. I will have him go on a scavenger hunt with his camera. I will say..find something red...and he has to go take a picture of it. Other ideas:

Find something square
Find something you love
Find something alive
Find something that belongs to your daddy
Find your favorite toy
Find a place you clean yourself
