Who Is Norbert Landsteiner and What Can You Find on masswerk.at?

Norbert Landsteiner is the founder of mass:werk, and masswerk.at is the corporate home page of that practice, covering design, web development, and consulting. It is a personal and company site rather than the official site of a single product, so the fastest way to use it is to treat it as a portfolio and demo hub: read About for background, browse Products & Demos for the work, and use Contact if you want to get in touch.

Who Norbert Landsteiner is

The site identifies mass:werk as the corporate home page of Norbert Landsteiner, with the listed activities of design, web development, and consulting. The site's own keywords also name N. Landsteiner as an alternate form of the name, alongside retro computing and computer history. That combination is the useful summary: a designer and developer who also builds and writes about historical computing.

If you arrived looking for a company with a large team or a product brand, adjust expectations. This is the working home of one practitioner, and the site is organized around his projects and experiments.

What the site is for

masswerk.at works as a navigation hub. The menu gives you the main areas:

The home page excerpt also surfaces a set of named demos and tools: Play Spacewar!, ELIZA, Talking PET 2001 Emulation, Virtual 6502, JS/UIX, Google BBS Terminal, and Google 60. These are the concrete things you can open and try, not just descriptions.

What you can actually do there

The demos fall into a few recognizable groups, which helps you decide what to open first.

Games and playable classics

Spacewar! is listed as something you can play directly. If your interest is early computer games, this is the most direct entry point on the site.

Emulations and conversational programs

ELIZA, the early conversational program, and a Talking PET 2001 emulation are both listed. These are reconstructions or emulations of historical computing experiences rather than modern applications, so expect period-appropriate behavior and interfaces.

Tools and technical experiments

Virtual 6502 and JS/UIX are listed among the tools. Virtual 6502 relates to the 6502 processor family, a chip central to home computers of the late 1970s and 1980s. JS/UIX is a JavaScript-based Unix-like environment. Both are the kind of thing you open in a browser to explore, not install.

Novelty and web-history pieces

Google BBS Terminal and Google 60 present Google-style interfaces in retro forms. They are best understood as design and web-history experiments.

How to use the site efficiently

1. Start at the Home page and read the menu, since the site is organized by section rather than by product.
2. Open About if you need to know who is behind the work before evaluating it.
3. Go to Products & Demos to see the full set rather than only the items highlighted on the home page.
4. Pick a demo by interest: games for play, ELIZA and PET 2001 for historical computing, Virtual 6502 and JS/UIX for technical exploration.
5. Use Contact only after you have a specific reason to reach out, such as a design, development, or consulting inquiry.

A practical check: if a demo does not load or behave as expected, confirm you are on the current page for that demo from Products & Demos rather than an old bookmark. The site lists these as demos and tools, so they are meant to run in the browser.

When this site is the right stop

masswerk.at is worth visiting if you want to see the work of Norbert Landsteiner, try browser-based retro computing demos, or evaluate whether to contact him about design, web development, or consulting. It is not the place to look for product documentation, pricing, or a support desk; the site presents the practice and its experiments, and the Contact entry is the route for anything beyond that.
