Metal Sculpture Idea

So I have finally settled on my final idea for this semester.

I will create a water powered metal sculpture powered by rain, which will be left outside to rust and return to nature over the course of its life.

I envision a the top looking not unlike a mushroom cap, except on the lower edge a small trough will run around the diameter to channel the water to a single point. That single point will fill cups that sit below it on a sort of ferris wheel looking device. Which will in turn pull a hammer up and release it with enough force to sound the pipe bell's note. Build it correctly with measurements, it can tell you how much it has rained.

However in order to avoid the failing of last kinetic sculpture. I envision this entire piece being not bigger than a half sheet of notebook paper high and wide.

Revenge of the Kinetic Sculpture

So after days and days and days of thinking. I have decided to kinetic sculpture that is powered by a water reserve that stores the potential energy. This would solve my motion problem that I never overcame in my previous attempt. Gravity would provide a reliable and constant power source.

This does mean however that I need to redo my entire design contract. I want to something in the idea of the floating world from Japanese art. Mostly negative space with single simple elements floating in the composition.

But I want to use mostly wood and Bamboo to make in the style of Buddhist bamboo fountains.

I would that nice natural tones produced by the rhythmic action

Oh man do I have a lot of research to do

New *ahem* New Idea

So I am considering making a new contract for this term. My first idea involved Balloons suspending knives. To embody the duality of childhood memories, being sweet and innocent but also painful and delicate.
However due the abysmal failure are creating a kinetic sculpture in our Translations campaign. Has inspired me to actually create a working one. Although I do really want to work with metal and the forge more.
So with my newly discovered importance of curves in kinetic sculpture, I am hoping to create a kinectic sculpture from wood and steel.

So this go round.

Small scale to play with humans being large
Self powered or able to conserve energy enough to move of it's own volition
Have a rhythmic and memorizing appearance 

Materials, Wood, Glue and Steel

also this is cool
