It's the pointless and eccentric sites that I love, like LineRider for example. Well here is another.
(http://344design.typepad.com/)
It's called the DailyMonster. You won't waste too much time on this, it's not a toy like LineRider but it's great fun. Every monster has a fluffy wavey part to it and it took me a while to work out how that is done. I expect the primary teachers among you knew at once.
If you want to see any of them full screen there are sixty or so on YouTube. Just go to the YouTube site and put Daily Monster in the search field.
