A project of Brazilian MIT programmer/designer Marcelo Coelho from 2003 that is starting to see some buzz, the Art-O-Meter is a device that scores works of art based on the ratio of the length of time people spend in front of art work to the duration of the exhibition. It operates as a clock until someone stands in front of it, activating its motion sensor and timer; an LED screen displays comments and calculates a fone to five star rating based on the cumulative viewing time.

His recent work includes explorations with "computationally enhanced materials" and "kinetic and electronically animated garments".
