Koi Pond
There are a ton of different apps (short for 'applications') that can be downloaded to the iPod Touch or iPhone. Some are useful, some help pass the time, and some are just kind of fun. Noah & Emily especially like the app called Koi Pond:
I will never, ever, put in a real water feature on my property, but I thought it might be kind of fun to have one on my iPod. :-) With Koi Pond, the screen is filled with what you see in the image above, with full, realistic animation -- the fish even respond when you 'dip' your finger in the water. If you shake the iPod, it 'feeds' the fish -- little pellets appear in the bottom of the pond, and the fish eat them as they go by.
There are also sounds that can be added -- rain & thunder, birds, rushing water, frogs, and crickets. The other night when I was having trouble getting to sleep (because I have a cold and can't use my CPAP), I turned on the rain to help put lull me off into la-la-land.
If the kids see me on the couch with my iPod, I can pretty much count on them climbing on my lap and asking to play 'the fish game' -- it's not a bad way to spend time with my little rug-rats. :-)
