Recently I was standing in the Merchandise Mart when I noticed something new - a Bitcoin ATM! This ATM allows users to utilize Bitcoin to receive dollars in exchange, in that sense being a "regular" ATM.
This is a Robocoin kiosk. Here is a link to their site where they describe what you can do at this ATM. I like their example of someone in Argentina depositing their currency in Bitcoins to avoid the inflation (and risk of outright seizure) that Argentina faces.
If you are interested in Bitcoins, wikipedia has an excellent summary here.
