Soapbox Science is a public engagement event which involves doing computing in the open air without computers
I made two things to help this out: a set of flipbooks (to show video dynamically) and a shadow box which is an arduino powered cardboard box with coloured lights in.
This repo will hold the python script that makes flipbooks (actually, makes a latex file which will compile to a flipbook given a directory of image files in an appropriate location) and an Arduino file which will power a box of shiny lights (or rather, a neopixel ring).
They're both quite hacky programs but hey feel free to take them and do stuff:)
