ah cool. was being unobservant - very nice feature. yeah i'm quite familiar with bricklink hahaha as is my debit card.

most my parts come from www.bricklink.com the black part is what slides the teller security guard up and down, if you look at the difference between the photo of it pushed in, the teller screen is up and when its pulled out the screen is down. i will try to put comments to explain..

Woah! How'd you get so many of those $100 pieces and the gold bar pieces? The atms are very cool. What does the black bit at the back do?
