AcornCharts uses the Chipmunk Physics library. It is a fun way to show charts by drawing balls that falls down when you tilt the device.

This is just something simple I made to learn Chipmunk, but it's usable. Remember to pull the chipmunk submodule before compiling.


  • 2 Options - uses ball size or quantity to show difference in data size
  • responds to device tilting

To pull to chipmunk submodule, go to the root directory of the folder and run the following

  • git submodule init
  • git submodule update
