How do I wirelessly communicate with the arduino?

I got my arduino up and running in talking to the computer using Serial programming and I'm really excited about it! Now the next proof of concept is getting to talk to it wirelessly. Anybody know of any really cheap ways of accomplishing this? I just want to send information to and from the computer during its execution so that it could just be awesome. :wink:

It'd be nice to send at least 8 bits to it wirelessly. If possible, it'd be nice to do it quickly.

Also, does anybody know of any wireless ways to sending high-resolution video to a computer? I want my computer to process whatever visual sensory information that's associated with the bot that's actuated and controlled by the arduino.

wireless ways to sending high-resolution video to a computer?

This is a whole lot of different kettle of fish. Forget the Arduino for this.

Wireless video is simple enough but all the processing should be on the PC side.
