Parametric CAD + simulation / in the browser

Build the mechanism.Show the reasoning.

Hologram is a browser-based parametric CAD and simulation workspace for turning constraints into inspectable mechanisms. Generate the geometry, test the motion, and hand someone a model they can orbit without installing the app.

01 / THE WORK

Don't take the pitch on trust.

These are not screenshots. Each card opens a real generated .holo bundle in the read-only viewer, ready to orbit, frame, inspect, and share.

02 / FROM SCREEN TO BENCH

A gearbox has to leave the viewport.

The useful story is the entire loop: parameters chosen, tooth geometry solved, printable clearances called out, parts made, and motion finally earned on the bench.

FIELD FILM / TAKE PENDING

The gearbox story is being cut.

The finished take will sit here: parameters, print, assembly, first motion. Until then, this is an honest empty frame—not a dead player.

03 / HOW IT WAS BUILT

The process is part of the product.

Hologram is built by a mixed agent fleet working under one rulebook: narrow file ownership, tests that do not borrow a live app, and logs that separate what was verified from what was assumed. The operating model is not backstage trivia. It is the engineering story.

04 / NEXT SURFACE

Playground—coming this week.

A public place to try Hologram itself is in the build queue. There is deliberately no hollow button here today; the door appears when the surface is ready to use.
