The proposed concept for the Bb Blackboard Challenge is a compact, square emoticon box. It can feature a yellow Bb or alternatively, black or grey. The design's simplicity and fun factor lie in its construction using just three parts (with electronic components) secured by four screws. With dimensions similar to a credit card at 68mm x 55x18mm, it is easily portable and can fit into a pocket. The model has been designed using Solidworks 2013, and a detailed description is provided in the enclosed document.
