Its hard to explain to the non geeks why this competition is impressive. Imagine trying to make a working bicycle, spending only 50p. Or building a house, but you are only allowed 27 bricks and a door. As a comparison, this little image on the right is 1000 bytes – but both the apps below have been made with the same amount of space!

Just click on it and use the cursor keys to move the bouncing character. It’s not the world’s best game, but absolutely incredible work for such a tight coding challenge. You can read all about how Marijn Haverbeke made it on his blog.
There are lots of other entries on the site – you can browse a huge list of them, but I will leave you with my second favourite: a fully automated living ecosystem:

Watch it for a bit, and you will see the plants multiplying and growing, then being eaten by the worms and growing again. Check out the explanation and source code on the site.
PS. I eventually managed to include the code within iframes, using the excellent Iframe Embedder plugin. Using this you simply use the code [ifra me http://webaddress.com 200 800] which will put webaddress.com in an iframe with a width of 200px and a height of 800px. Thanks to the guys in the forums for that one!
