IamA (Practical Special Effects Artist, Industrial Designer, and currently Professional Tree House Builder) AMA!
My short bio: Hi Reddit, you may remember us as the folks who brought you the statues of Atlas, from Portal ll, or Corvo Attano's mask from Dishonored. Building tree houses and making monsters for a living is really fulfilling and mentioning it around reddit always seems to invite questions. I consider myself an expert in designing custom things to be actually constructed in a fast and detailed fashion, with a high level of craftsmanship. I use several different CAD programs, graphics programs, work with wood, metal, and plastic, and stay up on all the current prototyping an manufacturing technologies almost as a hobby. I am equal parts artist, scientist, and engineer. I was recently asked to do an AMA so ask away!
