One of the smaller forms of creativity that excites me is coming up with some new form of representation regularly.
This can be aptly described by the Google doodles phenomenon. Coming up with a new logo for each and every occasion is quite a creative challenge indeed.
As you can see from this collection of all the doodles so far, its quite an exhaustive list.
Another similar implementation was in the Bleach anime. For each and every episode of the anime, the screen which showed the episode number had a different design.
It quite an array of numbers but no two with the same design. That is quite a feat in my book.
