For my 2D physics interaction, I made a squishy frog head that drops through platforms controlled by the mouse. A collision with each platform causes the frog to play a different note. It was created with Processing, Daniel Shiffman’s Box2D-for-Processing, and the SoundCipher library. 

I struggled with coming up with an idea for this assignment because I wanted to make good use of the physics library, but wasn’t sure how to make something interesting and fun to interact with. At first the frog was just a rigidbody, but I took inspiration from this video to make a circle out of distance joints instead. I think the squishiness really improved the assignment, and I’m glad that it allowed me to play with the physics a bit more.
