click on the link ↑ (up there)
click to make a shape. post your stage pics here! here are some I made: 1, 2, 3, 4, 5, 6.
nice project, the way the shapes appear is very smooth
it's so smooth because it's a "turbo drawn concentrated spiral". (I made that name up)
I ended up changing your code so that "concentration" was set to 0.5 and the number of sides is reduced to 50, so that I could actually see a spiral (rather than a filled polygon). I like spirals!
Also maybe change the turn angle to (360/sides)+(random from -3 to 3).
uh–that gives a weird result.
I didn't mean to suggest that you had to do it my way, just that I found a way to remix your project for my own amusement.
Where is the project ?
those extra ones were for testing. deleted.
Nice! Here's what I've made:
Oh btw did you make any updates to it? The shapes seem thicker than from what they were last time I visited it.
reload the project 
what happened is I accidentally increased the numbers in the for block. the first number is the # of sides of the shape with the least number of sides the program will draw, and the second number is the # of sides of the shape with the most. number of sides the program will draw
Here's the alternate version:
