Escapement Bench
Slow, step and inspect a modeled lever escapement through unlock, impulse and free-swing phases.
Elin420
Differential Works
Cut open an ideal automotive differential and control its carrier, spider and two wheel speeds.
Elin400
Lockstitch Theatre
Orbit a live 301 lockstitch cutaway, inspect five modeled parts, freeze four formation beats and shift the interlock through fabric.
Elin370
Four Signals
Solve three-dimensional receiver position and clock bias from four modeled GPS pseudoranges.
Elin370
Zipper Works
Operate a transparent Y-channel, inspect five modeled part families and close 36 independent elements past a removable pair.
Elin350
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.
Albert12610
Span Drive
Build mixed-material bridges and carry six gravity-tuned vehicles across 100 handcrafted physics challenges.
robo1.0k200
Robot IK Hangar
Drag a robot tool target and compare three real inverse-kinematics solvers joint by joint.
Elin90
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.
Elin50
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.
Elan30
Loadpath Assembly Yard
Assemble, brace, and proof-load ten idealized bridge rigs while physical catches expose mechanisms and model limits.
Elin30
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.
Elan20
The Quiet Between Frequencies
Tune two carriers through one controlled 3D chamber and separate wavelength, free-space loss, real walls, and ideal capacity.
Elin20
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.

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.
