Some years back I had this project: Thumbs Up! A website dedicated to images having people showing thumbs up. I stopped with the project because I needed to switch my sites to a new web server without PHP support.
At random times people would ask me when the site would be back up.. I kept promising..
Today is the day! I ported the project to Googles App Engine, making it more stable ;) I already uploaded all old images making it a fun browsing thing already.
Note that this is just the initial port.. I have some stuff to do and will add some features..
Now go to http://thumbsup.tk! Have fun!
