Hidden Heat approached us with only a couple of requirements, one being "we want something different, with the wow factor" and secondly "can we have 3D animated pipes please?". Pipes are all well and good for a Windows 98 screen saver, but don’t really cut the mustard these days.
So, we gave them their pipes, but then built a highly detailed, realistically lit studio to put them in that their visitors could interactively explore. Stick that in your pipe.
