Looks pretty useless. Fun for about 5 minutes.
And I still give them all the thumbs up I can. It's the fun in doing things like this that leads to enjoyment in creating for the computer world. And enjoying what you do is the key to making something amazing. Maybe these folks will not, maybe they will. But they are in the right track.
Have done pretty useless things in my past also, and enjoyed them a lot while doing and while seeing the "finished" product.
