Hacking away at the Labs is awesome. This? It's just tinkering with the UI. There are a gajillion different key word searches they could do; tilt tilts the screen, scary ghost scream waits ten seconds and then flashes a scary ghost on the screen with a scream; etc etc.
And, while they're doing that, and Google just works for most people there are a small group of users who'd really appreciate better documentation for searching. Wanna-be power users need to know how to combine terms or have options or how to use stemming etc. I dunno why a single page of instructions with examples is so hard to get.
