Combining traditional painting and projection mapping using processing and arduino for the ultimate interactive art experience.
The structure of the canvas, mixing colors right on the canvas, layer after layer and letting the coincidence help is what makes traditional painting so powerful. However, as a nerdophile person I often miss the undo button and the color wheel of the digital world.
Luckily, I came across the processing movement turning code into art and vice versa. The perfect base to combine vivid richness of painted structure with the interactive and dynamic power of code. In fact, I had the idea of creating a painting hanging in a local club and each time someone enters or leaves the room the color palette of the painting changes.
The Twetterhäuschen has its web form (index.html) to fill a brand or topic of interest
The keyword is passed on to the server (app.js) which takes care of the API calls using the oauth module. The search is completed with some words to derive a basic level of sentiment, e.g. “love” or “hate”
Taking the reach (number of followers) into account, the ratio between good and bad is calculated
The arduino sets the servo between the angle of 60 and 130 in order to move the two characters Sepp and Susi out of the Twetterhäuschen.
Whereas Sepp represents the dark force, Susi acts as a substitute for ecstacy and elation.
