IGoogle is a blast. You could spend hours adding games etc. The themes are awesome you can change it to fit your mood each day or week. Its handing for placing all the things you like to use daily or weekly even monthly in one spot. The minimising button helps keep the page from being to cluttered. Being able to move the boxes is great it enables you to place the ones you use more regularly at top and the ones you may only use occasionally down the bottom.
If I had the brains I think it would be great to work for google - free food, a gym, no uniforms although I am sure they would need to produce TOP ideas to stay there.
