An artwork showing at this year's Frieze Art Fair in London is putting the crunch back into credit. Michael Landy's ‘Credit Card Destroying Machine' is made from a metal structure together with found objects, cogs and wheels, and even the occasional stuffed animal. On one side is a sketchbook on which the machine ‘draws,’ a slightly erratic spirograph style drawing using a felt tip pen of your choice, but in return for this one off artwork, you must insert your credit card to be crushed. A previous incarnation of the piece was seen at the opening of the Louis Vuitton flagship store on Bond Street, where it offered to chop up the credit cards of those shopping in store.

Landy’s piece is in the Thomas Dane Gallery at the Frieze Art Fair, which is running until Sunday.
