I break ciphers for fun

• I solved a newspaper ad from 1897/.
• I also cracked a KKK cipher from 1918, in the process becoming the first person to solve a level X cipher on mysterytwister where I was once ranked 3rd in the world despite starting years later than the leaders.

I've been designing and building planetariums/planetaria/"orrerys"/"orreries"

• Heliocentric "Impossible Planetarium" with no nested axles at all and no visible moving parts.
• Solution for Antikythera mechanism with no extra nested axles (vs 11-way nested axle)
• Solution for Antikythera mechanism with even less gears and no extra nested axles
• Lego Eudoxus of Cnidos model
