Check out this Portable CNC in a Box (translated into English). If you ever wanted to setup a CNC machine in a mall on the weekend at a small booth this would be the ideal machine for that. Just think of all the custom trinkets you could make with it. Best of all the steam punk controller which reminds me of the Wiimote remote would make it look like you were doing more work than just jogging the bit into the start position. At a quick glance it may look like a simple plywood box that holds a milling machine. With a closer look you can see that there is a monitor built into one of the sides, all of the motor controls are built into another section and finally all of the computer electronics are also crammed into the case.
