OK. Don't read past this first paragraph yet. I want you to look at the pic above and try to guess what's going on. Go ahead. I'll be here when you get back.
Figure it out? I didn't. At first I thought it was some kind of "Internet-speak joke" that I'm not hip enough to get. Thankfully, it's something much cooler.
By way of Lifehacker, I bring you the Spider-Mac desktop. Not its official name (not yet at least). Basically one of Lifehacker's readers, Zack Shackleton took a Spider-man comic panel and made a useful desktop background out of it.
Using a number of diagnostic and editing tools including GeekTool and Magnifique, he pulled a bunch of info from his Mac (like the time, a to-do list, calender, and CPU info) into an impressive dynamic package that displays this data as word balloons.
This makes for a fun desktop (albeit a confusing picture if you don't know the context) for the Mac. Actually, the first thing I thought of when I saw this was the Get your War On comic and those G.I. Joe public service announcements from a few years back.
