I just tried to use bezierPath.polygon()
since bezierPath.rect()
and bezierPath.oval()
work.
this does not work (and can be solved in other ways), but maybe it would be nice and somewhat logic since rect and oval do work?

bezierPath.polygon()?

RE: How can I split a path into multiple segments?
@jansindl3r keep in mind that in a Bezier curve time and distance do not correlate. if you construct a point at time .1 it will not be at one tenth of the curve length.
afaik the most common technique to get similar distances is to calculate lots of points on the curve(s), calculate some distances and select the closest points.
this link has some very helpful information.
good luck.

RE: Output text
@gferreira
probably not pythonic
but i was surprised this works
(if you keep things black and white)coin = randint(0, 1) color1 = coin, color2 = not coin,

Lissajous table
Here is some code to draw a Lissajous table.
Change thefunc_x
and/orfunc_y
(sin or cos) and/or add some value to thedelta
to get other curves.
Well, actually the curves are just polygons.#  # lissajous table #  # settings cols = 12 rows = 8 cell_s = 80 r_factor = .8 # fraction of the cell size to have a gap between them func_x = cos # should be `sin` or `cos` func_y = sin # should be `sin` or `cos` delta = 0 #pi/3 # some angle in radians density = 360 # amount of points per cell – higher values make nicer curve approximations #  # calculated settings radius = (cell_s * r_factor) / 2 step = (2 * pi) / density pw = cell_s * (cols + 1) ph = cell_s * (rows + 1) x_coords = { (col, d) : func_x(step * (col + 1) * d + pi/2 + delta) * radius for col in range(cols) for d in range(density) } y_coords = { (row, d) : func_y(step * (row + 1) * d + pi/2) * radius for row in range(rows) for d in range(density) } #  # function(s) def draw_cell(pos, col, row): cx, cy = pos points = [(cx + x_coords[(col, f)], cy + y_coords[(row, f)]) for f in range(density)] polygon(*points) #  # drawings newPage(pw, ph) rect(0, 0, pw, ph) fontSize(12) translate(0, ph) fill(1) text('δ\n{0:.2f}°'.format(degrees(delta)), (cell_s * (1  r_factor)/2, 20)) for col in range(1, cols+1): cx = col * cell_s + cell_s * (1  r_factor)/2 text('{0}\n{1}'.format(func_x.__name__, col), (cx, 20)) for row in range(1, rows + 1): cy = row * cell_s + cell_s * (1  r_factor) text('{0}\n{1}'.format(func_y.__name__, row), (cell_s * (1  r_factor)/2, cy)) fill(None) stroke(.5) strokeWidth(1) for col in range(cols): for row in range(rows): draw_cell((cell_s * col + cell_s * 1.5,  cell_s * row cell_s * 1.5), col, row)

RE: How to mirror/flip a object?
@habakuk nice to read that you can use some of the code!
about the lissajous: I am not sure what exactly you want to achieve. the german wiki entry has vizualisations for a few values. you might want to change the value for
a
andb
and alsodelta
, eg:a = 1 b = 3 delta = pi/4
I do not have your variable font so I cannot test this but I was wondering why you added the plus and minus 20 here:
curr_axis1 = ip(axis1_min + 20, axis1_max  20, x) curr_axis2 = ip(axis2_min + 20, axis2_max  20, y)
lastly if you want to draw the shadow in the back, just put the lines of code before you call the pink drawing. you might then use the
savedState()
so draw it without the mirroring.good luck, jo!

RE: How to mirror/flip a object?
the mirrored drawing is probably happening outside your canvas. keep in mind that every transformation (scale, skew, rotation, etc) is always starting from the origin. so a mirroring from the default origin (left, bottom corner) will be to the left or below your canvas. see the example below with a shifted origin.
pw = 1000 ph = 400 txt = "SHADE" newPage(pw, ph) translate(0, 160) # shift the origin up a bit fontSize(300) text(txt, (pw/2, 0), align = 'center') scale(x=1, y=.5) # the mirroring text(txt, (pw/2, 0), align = 'center')

RE: More variable fonts nonsense
@Christine hello!
I just downloaded the zip from github and did test a few of the scripts in drawbot without any issue. did you change the folder structure and / or do you get an error message? what OS are you using? 
RE: Random Lines with no intersection
ok if i got you right you want the function to
return
a value — in your case the height of the legs. this value could then be used in awhile
loop. while loops are quite helpful but might run forever if done incorrect. I adapted the code a bit so the legs function returns the length of the legs which is then added to the y value in the while loop. There is a check inside the while loop so it will run for a maximum of 3000 times.#  # settings pw = ph = 500 amount_x = 10 cell_w = pw / amount_x max_h = 50 gap = max_h * .2 #  # fucntion(s) def legs(pos, max_w, max_h): x, y = pos length = random() * max_h step_s = random() * max_w polygon((x  step_s, y) , (x, y + length), (x + step_s, y), close = False) return length #  # drawings newPage(pw, ph) fill(None) stroke(0) strokeWidth(2) for x in range(amount_x): count = 0 y = random() * max_h while y < ph: y += legs((x * cell_w + cell_w/2, y), cell_w/2, max_h) y += gap count += 1 if count > 3000: break
and the while loop without the check:
for x in range(amount_x): y = random() * max_h while y < ph: y += legs((x * cell_w + cell_w/2, y), cell_w/2, max_h) y += gap

Vera Molnar recoded
Vera Molnar is a great computer generated arts pioneer and is still working. I could not resist to emulate and try to recode some of her artworks. Using drawbot to do so is great fun and pretty easy — one can only wonder about the struggles she had to overcome. With all due respect here is a link to github with my humble attempts.

Solar eclipse
if you are not in chile or argentina for the solar eclipse this code can gif you solace:
#  # settings pw = 800 ph = 500 dia = pw * .45 frames = 20 #  # function(s) def a_page(): newPage(pw, ph) rect(0, 0, pw, ph) radialGradient((pw/2, ph/2), (pw/2, ph/2), [(1, 0.8, 0), (0.9, 0.6, 0) ]) oval(pw/2dia/2, ph/2dia/2, dia, dia) def ip(a, b, f): return a + (ba)*f #  # drawings for frame in range(frames): a_page() f = frame / frames x = ip(pw/4, pw/4*3, f) y = ip(0, ph, f) fill(0) if abs(x  pw/2) < .2: shadow((0, 0), dia/3, (1, 1, 1)) oval(x  dia/2, y  dia/2, dia, dia) # saveImage('solar_eclipse.gif')
