Picture generator

Make unexpected 3 by 3 pictures using a difficult and elongated mechanism (albeit with an easy working principle), which contains 93 command blocks. Examine the structure of the fixture, add and change colors, in order to create a random pattern.
The system contains a clear function, therefore, if the image starts to change colors infinitely, press the "Clear the canvas" key on the right side.


If you want to create a picture, click on the "Draw a picture" button on the left ".


If you want to see how this mechanism works, head up and study.
