Random Walk Fractal Tree

I had just finished watching your video on random walkers, and you started suggesting your ideas for what you can do with those, such as music compositions and various other things, but what about a fractal tree? I had also watched your fractal tree videos and wouldn't it be possible to create a random walk algorithm and based upon that make a fractal tree?

Example 1:
The random numbers go from 0 - 3 and it's rounded with a floor().
0 will draw a line, 1 will turn right, 2 will turn left.

Example 2:
Like before it'll generate numbers with a floor() around it but this time it's 0 - 5.
0 will draw, 1 = turn right, 2 = turn left, but 3 saves the last position and 4 will load that position kind of like your L-System fractal tree. So if it generated 0, 3, 1, 0, 2, 4, 0, it would draw, save that position, turn right, draw again, then turn left, then go back to that previous position and draw another line, then continue from there.

I would love to see this done, and I would do it but I'm not a super experienced programmer like you. Thank you for your time.
