On first sight, the Octocube is all smoke and mirrors. You could spend quite a while trying to figure out what it is or does. Go on. See if you can figure it out. If you cant work it out from the pictures alone then how about the name. Octocube. Any help? The sharper eye will observe the 2 cables/pipes at the rear so surely it does something right? Designer Vivien Muller has created this little mystery for your Thursday morning enjoyment. Give up? Entirely created from a single 90 degree elbow, the Octocube builds up into a radiant heater with a large surface area, and the inherent flexibility and modularity of the elbow. It is designed to be a sculptural heater that fits in with any interior.
