This animation is made with points in a Python collections.deque data structure, added by dragging the mouse (code bellow).

from collections import deque # a double-ended queue import py5 # check out https://github.com/py5coding  history = deque(maxlen=512) # mouse dragged positions def setup(): # py5 will call this once to set things up py5.size(600, 400) py5.no_stroke() py5.color_mode(py5.HSB) def draw(): # py5 will call this in a loop py5.background(51) for i, (x, y) in enumerate(history): py5.fill(i / 2, 255, 255, 128) py5.circle(x, y, 8 + i / 16) history.rotate(-1) # Thank you Ramalho! Previously `if h: h.append(h.popleft())` def mouse_dragged(): # py5 will call this when you drag the mouse history.append((py5.mouse_x, py5.mouse_y)) def key_pressed(): # py5 will call this when a key is pressed history.clear() py5.run_sketch()

• 🔭 I have just finished a PhD at Unicamp by the end of 2025.
• 🌱 I have very little idea of what I'm going to do now...
• 💬 Ask me about drawing with Python!
  • Check out py5 and my modified pyp5js hack, they bring in the vocabulary from Processing & P5js!
  • I try to make a new drawing with code everyday, and I put the results at skech-a-day.
• 👯 I’d like to collaborate on open resources to teach programming.
  • I collect tools for teaching Python in a visual output here.
