If I hadn't seen it ...
Shrink a tumbling sphere? A rose, obviously.
fullscreen float a=0;void setup(){size(600,600,P3D);}void draw(){translate(300,300);strokeWeight(3);rotateY(cos(a));stroke(229,0,54,20);rotateZ(sin(a));fill(1,150);box(200-a*10);a+=0.005;if (a>20){a=20;}}
Tweaked my alien egg sketch by replacing 'sphere' with 'box' and got this - I love these lucky accidents with Processing! Similar in output but different in code to Callum Rogers' 'Rose generator', which I really like. Submitted for the 'Tiny sketch' competition.
