One of my clients, Doordeck, had the enviable benefit of having an in-house laser cutter. One Christmas, to push the boat out and do something memorable for their clients and customers, I tried to recall my secondary school DT lessons and ending up designing and cutting these cute little 3D Christmas tree cards, which could be posted flat. Also, it spurred me to create this video, which has perhaps some of the most satisfying shots I've ever filmed (especially at 0:30.)
