There are thousands of (work safe) webcams out there, some so people can watch their pets or pickup trucks while they work, others for scientists, corporations or tourism (nice Christmas Tree.)

Here's a specialized Google search that pulls up cameras using a certain software, many of which can be panned or zoomed. Different locations are active at different hours. Be warned: it's a time killer. Don't get started unless you don't have a lot to do in the next few hours.

For example: Watch this Hong Kong gambling club in case someone tries to rob the place. Or this electronics store in Italy. Or people sipping tea outside of this Starbucks in Japan. Or the crowds on the plaza in Macau. Or this tennis court somewhere in Asia... see what I mean.
