The Blast Furnace went through a couple of incarnations from the start of the game to the current model. They both had the concrete core but the preipheral design changed a bit, and for the better over time. The original had a bit of a weird design which was my doing and in hind sight not the best, but you learn as you go. The new improved model you see here makes a lot more sense as a functional machine. This new design still defies traditional designs somewhat and has a unique look which we wanted. I really enjoy thinking about how a device will function logically and designing it with that in mind. This leads to a device that players/viewers can readily accept as a real thing that would actually work. For Hurtworld we felt that the art should suspend disbelief and so this was a vital design principle that I maintained in my work.
