Hypnotic Egg

To create an intriguing earthy theme, I chose an egg as my inspiration piece. The mystery revolves around an inside-out fabricated egg design. There are just two components that need printing thrice each. These interlocking spirals are tied together using a string which ascends to the three locks without requiring any tools. To secure the string, a knot is made at one end and then pulled from within to the bottom hole on the lip of the first spiral section. The string winds around the second section before being reinserted into the same hole of the third section. Finally, it passes through the top hole of the third section to reach a lock and gets knotted to stop. Additionally, I incorporated shadows as a fourth dimension, playing with them both on the ground and within the egg. Thinner spirals carved inside the egg and a rotating spiral on the ground enhance this effect. By positioning the fixed point above the shade, one can wind up the shade and witness a hypnotic shadow play below as it continuously winds and unwinds.
