My super creative engineer friend Ragnar recently introduced me to one of his latest projects - the Drawer Bot. Some algorithms on a computer tell the device where to scribble (coordinates) and at what intensity (number of pixels) based on a digital file. The pen moves diagonally and the effect resembles the style of an old school letterpress. You can simply insert any pen and have it draw any picture or piece of text you want. With basic code, you can set it up so that tweets and photos can be sent directly to the Drawer Bot. I love it!
