Colorful geometric paintings

Recently I’ve come across a series of unusual paintings of brightly colored geometric patterns pasted to the wall in various parts of the city. The first one was stuck to a building near Slim’s. The other two were pasted to the side of the Victoria Theater.

What are these paintings supposed to mean? Who’s behind them? We may never know for certain, but personally I’m hoping they’re a new type of QR code left here by aliens. So please let me know if you see an app for scanning alien QR codes on your phone’s app store. Thanks in advance.
