~ the last words ~

Edusim was a free 3D virtual world made to be touched. Richard White, a researcher at the Southeast Kansas Education Service Center in Girard, started releasing it in September 2007 with one specific piece of classroom furniture in mind: the interactive whiteboard that districts across the United States had just finished buying. Most educational software treated that board as a very expensive projector screen. Edusim treated it as a surface you could reach into, so a class could drag a dinosaur skeleton around by hand at wall scale.

Underneath, it was Squeak. Edusim ran as a modified edition of Open Cobalt, itself the open-source descendant of the Croquet Project, which means a Kansas middle-school lesson about how birds fly was being rendered by the same peer-to-peer Smalltalk machinery Alan Kay's group built to replace the desktop metaphor. The code went out under MIT and the media mostly under Creative Commons, with an authoring toolkit attached so a teacher could build their own room instead of waiting for a publisher to ship one.

The pilots ran with sixth and seventh graders around southeast Kansas, and the concept got further than most one-person open-source projects manage. Smart Technologies shipped the first commercial Edusim interface inside their own 3D Tools product, which put White's idea on boards that had never heard of Squeak. Multiple classrooms could connect their whiteboards into a single session, so two schools at opposite ends of a county could stand in the same virtual room.

Then it stopped. The last substantive update to the site lands in early 2012, and after that edusim3d.com served a byte-identical page through every capture from April 2012 to October 2017. The host went away that autumn. The last real crawl is 4 October 2017 and by 26 December the domain was answering with a Sedo sale lander, with nothing in between: no closing post and no archive handoff. Anyone who finds the site alive around 2020 is looking at an SEO squat rehosting the 2008 homepage with spam links pasted into it.

~ the record ~

~ the hardware it was built for ~

Interactive whiteboards were a mid-2000s spending wave, sold on the promise that touching the screen changes how a room learns. The software that came in the box was mostly flipchart tools. Edusim was one of the few serious attempts to ask what the hardware was actually good for, and its answer was a 3D model big enough for a whole class to see and close enough for one kid to grab.

That tied its fate to a product category. Once schools moved to tablets and then to Chromebooks, the shared wall display stopped being the center of the room, and a virtual world designed for exactly one board at the front of exactly one classroom had nowhere left to go.

~ the five silent years ~

The strange part of the ending is how long it took anybody to notice. From April 2012 the site returned the same bytes every time a crawler came by, which means the project had been finished for years while its front door still said download. Open-source software rarely announces its death. It stops getting commits and then stops getting mentioned. Eventually a hosting bill goes unpaid and a registrar sells the name to somebody who wants the backlinks.

~ what got buried with it ~

Open Cobalt is in this graveyard too, and Teleplace, the commercial Croquet line, went before both of them. Edusim was the last member of that family with a public face, so its quiet expiry closed out a lineage of Smalltalk metaverse work that had been running since 2001 on the premise that virtual worlds should be authored by the people inside them rather than rented from a company.

Turkey bought the boards. The FATİH program put interactive whiteboards into state classrooms from 2011 onward, hundreds of thousands of them over the following decade, and by then I was long out of school and working. What never arrived alongside the hardware was anything resembling Edusim. The boards mostly ran the same slideware the projector had been running, which is the exact outcome White spent ten years arguing against, and losing to.

What survives is the pitch itself. Every few years somebody rediscovers that children learn a shape faster when they can turn it with their hands, and the version that ships is a subscription with a login screen. White gave his away with the source attached, from a service center in a small Kansas town.
