Simple particle system with gravity handles elastic collisions, and at speed relative gravity, and colors particles based on speed issues: anti-clockwise rotation builds? it keeps going until the particles cant hold themselves together. and if you aren't centered at 0, 0, the new particles don't spawn correctly Click to place a particle, hold and drag to give starting momentum, Q/E for zoom control, W/S for top, down movement, A/D for horizontal. WORKS BEST WITH TW: more particles + HQ pen
