Having 28 members isn't really considered a big accomplishment in the demoscene :-)
I can get together a group with 28 members in a single demoparty. We'll all be drunk idiots who forgot we signed up the day after, but we'd be 28 members.
Many of the Farbrausch guys work or have worked in the game industry. In fact, for a long time .theprodukkt (FR's somewhat more elitist and commercially feasible spinout) was planned to become a game company, but it never really did.
The same holds for most other good demomakers currently active. The entire Finnish demoscene makes mobile games, the Norwegians all work at ARM to make mobile graphics chips, and p01 works at Opera winning js1k competitions.
Meanwhile, the only somewhat active Spanish demoscener left codes Three.js at Google.
ryg has been at RAD Game Tools for a while now, and mentioned yesterday on Twitter that he's been doing contract work on Valve's hardware experiments. [1]
While at RAD he's also worked on the D3D stack for Larrabee under contract with Intel and on optimizing the low-level graphics layer for Iggy (RAD's Flash-based UI middleware) across several platforms.
Their wikipedia entry lists 28 (!) members.
Did these guys work with any well known software/game companies/products?
