SHRINK
A free zoom game inside 32 real microscope slides, from the hooks on a bee's wing to a cell splitting in two. For curious children about 7 to 12, and anyone older. Progress stays in your browser; nothing is sent anywhere.
X-WOW
X-WOW began in 2018 by sending microscopes, slides and lectures to people who had none. Today it makes free, open ways to see the world more closely: a zoom game inside real microscope slides, and a design for a cheap microscope that anyone may build.
Origin
X-WOW began as the Pathology Without Borders Initiative. From December 2018 its founder found microscopes new homes with people who needed them, seven by the old site's count, and began asking labs for the retired ones gathering dust. In 2019, kind people chipped in for a low-cost slide scanner, so doctors treating children with cancer in Malawi could share slides with colleagues about 11,900 km (7,400 miles, as the old site put it) away. Scanned biology slides went online free, for students who have no microscope, and a student in Abuja who helped went on to start a kids' science club. When classrooms closed in 2020, scientists gave free online lectures to students across Africa and beyond, part-funded by the Royal College of Pathologists' Public Engagement Grant.
What those years showed: a microscope in a cupboard helps nobody, and neither does software that needs a powerful computer. Tools have to be light and cheap to reach people. So X-WOW now goes beyond pathology and old equipment: it designs its own ways to see more closely, in the open, and gives them away. SHRINK and SWELL are the first.

A design for an automated expansion microscope, meant to be cheap: swell a sample of chicken muscle a few times bigger in a gel, image it with modest optics, and use the muscle's own stripes to check the result. Designed and simulated, never built.
The next invention will appear here once it has what SWELL has: a design, a parts list, safety notes and a plain list of what isn't known yet.
Why it is free
X-WOW's founder isn't interested in money, fame or research credit, and would rather see these ideas built than see a name on them.
If you build one, it's yours. Improve it, publish it, teach with it, and you're welcome to claim the success. CC0 lets you sell it too, but it can't clear anyone else's patents or the safety rules for selling a device: each invention has a legal note.
Each SWELL number carries the simulation file or document line it came from. Point at, tap or tab to a dotted number to see its source.
SWELL's blind test, on a synthetic gel made separately so the answers weren't known in advance, failed 3 of its 7 headline checks. The technical record shows each failure next to the passes.
Design notes, simulations, data and code in a single download. Text, data and code are CC0, except quotations and licence texts; hardware is CERN-OHL-P; the X-WOW name and logo are excluded. No tracking.
From the archive
From 2018 to 2020, X-WOW ran lectures, a kids' science club and free teaching material, and shared digital slides and a slide scanner. These pages keep the record and credit the people who made it happen.
