Where else do i have to alter sizes?

Thanks

How in the world did you come to

transition((current.id+(slides.length-2))%slides.length+1);

in the prev()-function. This is sooo clever

To make the tiles appear randomly, you will need to modify line 35 of scripts.js – Part 2. It is currently:

},i*10);

This means that each tile is show 10 milliseconds after the previous. To make it random, you need something like this:

},Math.round(Math.random()*50)*10);

Great tutorial, keep up the good work!
