Playing With Movement: Oscillators: Springs
While at one of my favorite Wild Hare Ideas Parts sources - ACE Hardware (aka Los Gatos Hardware) - looking for a range of sizes of ball bearings for The Rain Stick - which, it turns out they carry - the set of little drawers next to them had - springs - little to medium sized springs - all sorts of medium to little sized springs - of different types.
I didn't realize how many kinds of springs there are - springs to be stretched, springs to be compressed, springs to bend and snap back - springs with loops to attach them with screws, springs with hooks on the ends to hang things from - springs from round wire, square wire and flat wire. Springs, springs and more springs in all sorts of sizes.
Springs - something springing - up and down - in and out - left and right - AND - springs SPROINGing - in all sorts of directions.
Springs are a type of oscillator - hmmmmm.
I'd used straight spring wire for adding movement to a turned piece - why not try using - springs?
