Considering the game shapes and colors as if it involved physical objects is difficult, to say the least as what can be done in the game could never really be accomplished with physical objects in the real world. However, as the title describe we are dealing with shapes and colors. More specifically we have various different circles and various different triangles. There is also the ability to draw lines free-hand. Essentially what we are dealing with leans more on the chunky block-like painting than any granular or smooth painting. This is more closely related to rapidly printing a shape with occasionally changing the size or dimensions of the shape. There are also options to alter the color at random but overall the stuff manipulated is very blocky. The exception is the free-hand line drawing tool that is very smooth. The tools with random elements very much do have a life of their own where the randomness creates a sense of personality that is not controlled by the one manipulating them but happens regardless. There is also a discernable pattern with repeated shapes and colors in certain areas. A real-world recreation would be very difficult to produce but I might be able to. One way would be to give the person a shape dipped in paint that they can press down shapes. The dragging function in this game would likely be lost, but the random color and shape functions would be produced by periodically switching out the player's tools. Overall I don't think this could be recreated with physical objects without losing out on core aspects.
