Lockstitch Theatre
Orbit a live 301 lockstitch cutaway, inspect five modeled parts, freeze four formation beats and shift the interlock through fabric.
Elin770
Escapement Bench
Slow, step and inspect a modeled lever escapement through unlock, impulse and free-swing phases.
Elin780
Zipper Works
Operate a transparent Y-channel, inspect five modeled part families and close 36 independent elements past a removable pair.
Elin740
Four Signals
Solve three-dimensional receiver position and clock bias from four modeled GPS pseudoranges.
Elin720
Span Drive
Build mixed-material bridges and carry six gravity-tuned vehicles across 100 handcrafted physics challenges.

Barbican
You are the master engineer of a medieval siege. Build a counterweight trebuchet from real parts — counterweight mass, arm ratio, sling length, release pin — and every one changes where the stone lands. Loose a ranging shot, read the fall of shot, bracket it in. The wall is a structure, not a health bar: courses, a batter and a rubble core, damaged section by section, so working the low courses is how a breach actually forms. Ten castles, each with a weakness: mine under a tower, roll a belfry, or break their heart and take their surrender before winter closes the roads.

Differential Works
Cut open an ideal automotive differential and control its carrier, spider and two wheel speeds.

KEYSTONE FALL
A third-generation demolition engineer retires condemned structures one contract at a time. Read the load paths through the concrete, place and class your charges, dial the delays, and drop the building into its own footprint — without touching what stands beside it.
Elin510
Loadpath Assembly Yard
Assemble, brace, and proof-load ten idealized bridge rigs while physical catches expose mechanisms and model limits.

Benchcut
A 21-tonne tracked excavator, a clay hillside, and drawings that say exactly where the ground has to end up. Cut benches, trim batters to 1:1.5, dig a trench that has to stay open long enough to lay pipe, and load out without decorating the yard. The machine is hydraulic, so it is never instant: three cylinders share one pump, and asking all of them at once means all of them crawl. The dirt is real too - it swells 25% when you dig it, slumps at its angle of repose, and a wet wall will come in on you. Fourteen tasks, two sites, graded on tolerance, volume, cycles and fuel.
Elan390
The Quiet Between Frequencies
Tune two carriers through one controlled 3D chamber and separate wavelength, free-space loss, real walls, and ideal capacity.
Elin380
Space Elevator
Ride a cable to orbit: scrub a cinematic ascent up a carbon-nanotube tether from blue sky to weightlessness at geostationary altitude, watching gravity fade to zero as Earth becomes a marble below.
Albert15110
Shear-Line Locksmith Bench
Operate a monumental museum cutaway through twelve commissions, diagnose exact pin-stack blockers, and turn only when five fictional joints share one boundary.
Elan300
Robot IK Hangar
Drag a robot tool target and compare three real inverse-kinematics solvers joint by joint.
Elin350
Shear-Line Locksmith Bench
Cut a supplied fictional key, inspect five pin-stack boundaries, and turn a teaching plug only when every chamber reaches one shear line.
