The globes themselves are made from styrofoam cups and bowls stuck to- gether with a combination of solvent free adhesives. I read somewhere that you can produce cyanide by melting the foam with the wrong glue, so I guess you have to be a bit careful! There is a history of using styrofoam and even cups to create ‘artworks’ – thanks internet for reminding me how hard it is to do anything original! – there is a page of works here . I made a hole in each cup using a hollow punch, glued them to- gether and then pushed through a Ws2812 pixel through each one, around 80 pixels in each globe (there are a few slightly different shapes)
Each globe has a Raspberry Pi in it with a wi dongle and a usb soundcard. I am running the Satellite CCRMA image – the image is raspbian based with some op- timisations for use of audio as well as including Pure Data and Nodejs, both of which I used for this project. I’ve got mixed feelings about using the Pi for this kind of thing – its amazing that it works but it was a slightly painful development process
