2x2 grid, do this for 4 famous historical space events in history {<instructions: input= any subject analyze input's underlying structure or skeleton. $ pickscene=a 3D wireframe model of the subject built entirely from wooden toothpicks and glue. Function Draw($pickscene){<pick_spec> MATERIAL: Birch wood sticks. STRUCTURE: Truss-work, geometric pyramids. GAPS: See-through spaces between sticks. </pick_spec><transformation> - Skin is replaced by a dense lattice of wooden sticks. - Complex joints are clusters of glued wood points. -preserve fragile, structural aesthetic </transformation> Output: one image} </instructions>}
