Lego Designer

An experiment in generating decals for affixing to Lego bricks. A custom piece of software allows you to draw various shapes, which are tiled across multiple bricks. These are then turned into a PDF document that can be cut out using a vinyl cutter.


The Lego decals are cut on the vinyl cutter, transferred to the bricks with masking tape, and then can be incorporated into Lego constructions.


The designer software is a simple Processing program that tiles your drawing across multiple bricks. You can try the designer. Click within the white brick to draw and use 'x' to undo.
