Chris Harrison and a friend built these motherboard walls for Carnegie Mellon University professor Scott Hudson:
Each motherboard wall took approximately 6 hours to assemble . The longest step by far was laying them out. Not only did we try to distribute the colors in an interesting way, but dozens of different sized boards had to fit together perfectly and not overlap the edges. Not an easy task I assure you. Additionally, we added a third dimension by stilting approximately one fourth of the boards at different heights.
