Introducing the Tessellation Kit. It’s a tool that lets you draw tessellations by pushing the edges of shapes into each other.

Just click on the canvas and drag the mouse around to extend a shape, and mathematics will take care of the rest. There a few buttons that let you change the shape of the tiles and the colors you are working with and a toggle for changing how the shape repeats.

Together they make it pretty easy to make something like this:

Despite it’s simplicity, it can do quite a lot. I used it to recreate this Alhambra tiling:

And this interlocking pattern  that Wikipedia tells me is ‘painted porcelain, china’:

The color schemes are generated completely randomly, so I’m sorry if you have to go through a few duds until you find one you like. I quite enjoy the feeling of finding a nice one that’s completely unique, so I didn’t want to just provide a few preset themes, or a simple generator that didn’t provide enough variety.

If you start getting serious, you might want to know that there are a few hotkeys and hidden features:

• ~ or h hide the controls
• z undo
• x redo
• e export to png
• -/+ zoom
• 1-5 operate individual controls.
