way to make a computer a wireless access point?

[stlredbird]

I just got an iPod Touch but don't have wifi at my place. I access the internet with a Sprint USB dongle plugged into my powerbook so I can't exactly hook up a wireless router or anything.

Is there anything that I can plug into my laptop that makes it a wireless access point that my iPod can access via wifi?

Thanks
