I wanted to play around with this stuff:
So I implemented a basic low res version for it
Made it so it renders ascii chars instead of circles
Then constrained it into the walls of a letterform. The sad part now is that the organic forms that the physarium produces is completely hidden now since it doesn't have the room to move...
But the motion is pretty interesting and organic.
So I just iterated a bunch on this
And I think this form looks awesome!
Going to turn this into a screen print :)
