I may have product-design blinkers on right now. But I see potential to develop this design in the direction of a more 'commercial' product. If there were five panels (identical and therefore easy to produce etc.) which fitted together (slide into eachother's tube ends) to make the circular arch, then the piece could be compact for packaging and transport (the arc segments laying in each others arc shape). And it could be sold in 'kit' form like this. Since the premise would essentially be an imaginary hexagon excribed by the circle, where the ground is the 6th edge of the hexagon, it would be what's sacred geometry to me. (There's something 'sacred' about being able to take a compass and divide the circle it's just drawn into exactly six segments with its radius.) It would need one other 'component type', the feet. And maybe.. maybe fixings and fastenings depending whether one could be clever enough about the design of the linking between segments. You could outsource production, because it would really be pretty simple to make. Tube bending might be the most complex process. And thus be able to get on with custom art works if that's what you prefer to be doing yourself. And have income 'happening' in the background while you do so.
