Yesterday, this appeared on my Mac desktop:
Here's a little movie showing you what it does.
Pretty weird. It's like a UFO.
I don't know where it came from or what it does.
Is it a virus? Spyware? Some undiscoverable bit of Mac UI?
If you know, please, people want to know!
Update: Intrepid reader Duncan Wilcox identified this as the "Floating Expose Blob"! Huh? I don't know what I did to turn this thing on, and indeed, it is yet another undiscoverable bit of Mac UI. Now I like the Mac as much as the next guy, but what's up with all these hidden features?
