week 7-8: progress

After the presentation, I find out what is the good way to express each and whole budget data.

I want to keep my light idea. This is rough sketch.

Each bar can express each budget data. There are leds. The led turn on and off by the budget data. Also, this can be room lamp. the whole bar can represent whole budget. I am not sure the idea which represent saving for an educational purpose. I can use whole led brightness. If brightness is high, people save money a lot. If not, it opposite.

This is a prototype of the final project it made by toothpicks.
