While wandering through the software developer forest, I find an abandoned booth—Google hasn't set up anything, and some weary-footed conference-goer is using their chair. A man from the neighboring booth tries to start Google's iMac. I fear the worst. Did Google forget about Macworld? Have they dropped all pretense of supporting Macs?

Google, it turns out, set themselves up with SketchUp, a 3D design brainstorming tool. SketchUp has a plugin for Google Earth, which came out for the Mac this week.

A Google employee demonstrates Google Earth by zooming in on "Saddam's former home."
