Google's Wonder Wheel is wonderful!

[BrainFreeze]

I'm just wondering if you guys have noticed the "wonder wheel" on google's new layout? When you search for something, like "chuck norris jokes", you can then click on the "wonder wheel" (on the left of the search results) and it will show you related searches. You can click on a related search, and then it will show new related searches for that search.
Seems like an awesome tool for searchers, but also for those of us looking for other related keyword phrases.
Have you guys tried it, and what do you think?

Wonder wheel's been around for quite some time - but you had to click "advanced options" to see it, in the new layout they display the options column by default.
