Summer 2001 was originally decorated with a heavy coffee beans image, which was later ditched for a more lightweight background.
The major features of this design included a semi-working portfolio, the 160-pixel image and "Idea3" apps - where you can build an isometric image from Tetris-style blocks.
Idea3 wasn't built Object-Oriented style, and probably would have benefited hugely (ie. the codebase) if it had been. Unfortunately I hadn't clued into that style of programming with Javascript yet - however, the app still works last I checked.
The K10K grid style was popular at the time and is demonstrated in the design.
