Computing Mechanisms and Linkages By Antonín Svoboda https://archive.org/details/computingmechani00anto

"He shows that with two basic mechanisms, the harmonic transformer and the three-bar linkage, it is possible to perform the fundamental operations of arithmetic, addition, subtraction, multiplication and division, and to generate ballistic functions." - JOHN WOMERSLEY (https://www.nature.com/articles/162085a0.pdf)

foehrenwald··on Blue field entoptic phenomenon
https://link.springer.com/chapter/10.1007/978-1-4613-8896-8_... "The inaccessibility of the retinal blood ves- sels precludes direct, noninvasive measure- ments of retinal blood flow. Indirect optical methods taking advantage of the visibility of the retinal vasculature must be used. A variety of methods have been applied.[...] Methods based on the perception of white blood cells (WBCs) moving in retinal macu- lar capillaries by means of the blue field entoptic phenomenon. Macular capillary blood flow is determined either by counting the number of WBCs passing in a given time through a single capillary 13 or by evaluating the average number and speed of WBCs in the field of observation using the blue field simulation technique.

foehrenwald··on The Cosmonaut of Potsdam
"It seems like when the Mosaic Panels of the Cosmos and the Cosmonaut (on the west side) were installed, the builders weren’t full paying attention as they had accidentally switched the position of the two outer panels and rotated one of them by 180 degrees. For the past 44 years, the slightly “abstract” cosmonaut mosaic has now been gracing the streets of Potsdam. It is somewhat strange though that in all that time – not even Eisel sought to correct the mistake."

Without any evidence, I find this notion somewhat naive.

"At 7 Gagarin Street, at the end of the South Ural State Technical College, formerly a polytechnic school, in Chelyabinsk, there is the panel "Space Conquest" (sometimes simply called "Cosmos"), one of the most important Soviet space-themed mosaics."

foehrenwald··on Open-Source Visual Field Examination Using VR Headset
From the article:

Currently, clinical static automated perimetry most commonly uses projection-based perimeters where a light source is projected onto a background of uniform intensity. Although this process can assess the visual field, it is tedious and uncomfortable for patients. Costing upwards of $30,000, traditional perimeters are large, bulky, and expensive with poor patient ergonomics.

We have developed a fully open-source, head-mounted display (HMD) perimeter capable of visual field testing that utilizes a Google Daydream VR headset and an Android smartphone (Samsung Electronics Co., Suwon, South Korea). With a cost of around $100, plus the cost of a consumer smartphone and computer, this system is portable and far less costly than traditional perimeters.

The Iowa Virtual Reality HMD Open-Source Perimeter is as repeatable as the Octopus 900 perimeter and is a more portable and less expensive alternative than traditional perimeters.
