Further progress on my indoor tree sculpture – testing out full-sized vellum leaves (with odd-coloured sheet), incorporating a more advanced balance mechanism, with branches constructed from foraged plastic sheeting. I think the proportions are off, but I’m very happy with the look of the leaves, with the pleating of the vellum nicely echoing the texture and transparency of real beech leaves. Next: tweaking proportions, testing addition of hinging to the branches.
I’ve made some progress on a background project that’s quite dear to my heart: a kinetic sculpture representing a beech branch with fresh new leaves. I’d developed some pleasingly fluttery leaf prototypes, but was struggling with how best to articulate the branches to replicate the way that a real tree sways in the breeze.
Given that my sculpture will be situated indoors, it will feel far lighter air currents than a free-range tree, so it must be correspondingly more sensitive. It must also grow up or down from a fixed point on a wall or ceiling, moving easily in the horizontal plane without drooping vertically.
My inspiration has come from a child’s toy – wooden or plastic snakes, with vertical hinges spaced along the body which let them wriggle freely from side-to-side when held up from the tail. These are often constructed using thread or fabric sandwiched between halves of the body, with cut-aways to allow sideways movement.
Irrespective of the angle of the branch, as long as the line of the joint is vertical, a branch will be balanced and able to swing freely. Smaller branches, down to the level of twigs, can be jointed on and articulated in the same way, and mounted at whatever angle suits. The range of motion of a particular branch is determined by thickness of material removed around its hinge.
This prototype is constructed from balsa wood and double-sided tape, using a ruler, set-square, craft knife, superglue, sandpaper, and a spare pair of hands.
The next stages will include larger-scale and higher complexity prototypes, as well as more materials tests.
