Animation app for TI Nspire graphing calculator.
The TI Nspire was the first platform I learned to code for. This app (like many others I wrote at the time) was written in Lua.
Using the touchpad, users can draw onscreen and navigate frames with directional arrows. The previous frame is shown with an onion skin effect. Shortcuts to duplicate, copy and paste frames are provided. You can also select entire shapes and drag them around.
Good for making rough animations during math class.
