This is a terrible first attempt to use the softbody processor to create a calculator. Left and right control the top input while a and d control the bottom.

As you can see how bad I am at using this program but, If anyone thinks they could make it better or make it do multiple calculations such as adding, subtracting, multiplying, dividing, taking the square root etc. at the same time it would probably be the most impressive scene on the site.
