Virtual Blather & Blarney:Virtual Peek & Stare:
Talk to My Cat
No, not my cat. I don't have a cat. Wouldn't mind having a cat, though ... but not his cat, because it's his.
The Corner of Hollywood & Vine
I think this is the corner where the Apollo 11 star is inlaid. I've been here a few times....
Columbia U Pepsi Machine
Now if they could only figure out some way to deliver the Diet Pepsi to my location.
Berkeley System's Kitchen Cam
See what those wacky engineers REALLY do with those toasters of theirs!

Announce your existence to the engineering blokes at work at Netscape. Pretend you're a bus....
Boston Back Bay WebCam
This isn't too far from both the neatest shopping area in the world, Quincy Market at Fanueil Hall; and the incredible memorial to the 54th Massachusetts, lyrically eulogized in the movie Glory. I'll stop gushing now, I promise.

I don't know what happened to this interesting device's link, but I've managed to fudge the tech to reproduce the connection to this complex virtual device.
Santa Monica Pier + Bay Watch
You know this place, even if you don't know you know. One of the most popular shooting locations in Los Angeles, the Pier also houses that terrific merry-go-round best known from The Sting.
WGN-TV Chicago
I finally got to visit Chicago relatively recently, and boy oh boy, what a neat city! The near-ubiquitous WGN provides some local color on the Web.
