The Construct turns a short video into a solid you can walk through.

You drop in a clip, say a cat crossing a room or a deer in a field. SAM 3.1 outlines everything in the first frame that could move, and you tap one subject or several. When you press Continue, SAM 3.1 tracks each of them through the clip. The Construct keeps every third frame, works out which way they're heading, and lines the poses up into a ghost trail that runs out ahead of them. Several picks share one trail and one direction for now. Scrolling moves you along that path through time. The current pose is solid, older ones fade out behind it, and fine light strands come off it square to the walls of an endless tesseract. A build takes well under a minute, and finished trails can be published as rooms you walk between.

It's for pet owners, wildlife watchers, naturalists and teachers who have clips and no 3D tools. A clip is flat and over in seconds. A ghost trail puts a whole gait or leap in front of you at once, where you can study it and compare one with another.

Live at https://www.thefourthtesseract.com. Sign up with any email; an 8-digit code arrives within a minute, and each person gets up to 25 builds a day. Prior work, disclosed: the spacetime-solid idea and the tesseract viewer. Built for this entry: the SAM 3.1 picking studio, Muse Spark clip checks, the ghost-trail pipeline and room, the strands, publish/approve/gallery, sign-in, quotas and build emails.
