Infinite Mac is a collection of classic Macintosh and NeXT system releases and software, all easily accessible from the comfort of a (modern) web browser.

Pick any version of System Software/Mac OS or NeXTStep/OPENSTEP from the 1980s or 1990s and run it (and major software of that era) within a virtual machine. You can also run a custom version with your choice of machine and virtual disks. Files can be imported and exported using drag and drop, and System 7 and onward have more advanced integrations as well – refer to the welcome screen in each machine for more details.

Rigs of Rods is an open source vehicle simulator licensed under the GNU General Public License version 3. What makes Rigs of Rods different to most simulators is its unique soft-body physics: vehicles, machines, objects, etc. are simulated in real-time as flexible soft-body objects, giving the simulation an extremely accurate behavior which entirely depends on the physical construction of the vehicles or objects you create. The community contributes greatly to the game, giving it a vast selection of vehicles and terrains from which you can choose.

KSP is a game where the players create and manage their own space program. Build spacecraft, fly them, and try to help the Kerbals to fulfill their ultimate mission of conquering space.

It is released to the public domain, which means you can modify it, redistribute it or use it however you like.

So what's wrong with using the Mac as a development machine for Milo, a Python application backed by PostgreSQL and Redis (or any web project, for that matter)? Well, sacred cow, here come the spears.
