Stickler is an interactive machine in the BTU Lab that dispenses custom-made stickers by CTD artists. This device serves as a means to spread student art around the ATLAS building, with a widespread reach facilitated by its evolving sticker selection. The distribution of Stickler's stickers will both literally and metaphorically leave a lasting impact on the campus community. Built primarily with Arduino, woodworking and lasercutting, this vending machine is designed to last, and with new sticker designs from new artists cycling in every few months, Stickler remains a constant source of art, entertainment, and community connection throughout ATLAS and the CU campus.
