Go to the Memphis Group Pattern Generator.
Generate fun Memphis Group-inspired patterns
This HTML5 project will randomly place, scale, and rotate pre-made shapes across two different design types, a more colorful style and a softer style. The .gif above shows different patterns being generated. When you find a design you like, you can press the Download button to initiate a download of the design 1:1 scale. This feature works as intended in most modern browsers, but may break on mobile devices. This fix, as well as seamless, tile-able patterns, are next on my to do list should I decide to expand.
Who is the Memphis Group?
Even if you don't know the Memphis Group, there's a good chance you've seen their abstract design influence. The Memphis Group were a 1980s design and architecture group based out of Italy. Founded by Ettore Sottsass in 1980, they crafted a wide array of art with a focus on furniture and fabrics.
