 Simple solid colors, gradients and test line patterns, could be used to test matrices for proper operation, flickering and estimate fillrate timings.
 
+It is also used in CI test builds to check different build flags scenarios.

 Should be build and uploaded as a [platformio](https://platformio.org/) project
