Projects.

I develop tools for all kinds of purposes and fields – building a house, organising documents, email, AI, games and more.
These projects are already online – each with its own website, most of them with a video too.

Every project has its place at a station in the alpine world, and related tools share one: “Take me there” drives you straight to it. More tools are on the way.

Construction Site

Sleeves up. Building in progress!

For my own home I developed tools that helped me plan and build it. Rotstift.io is one of them. Here on the construction site you can also operate the excavator and the crane yourself.

  • Drive the excavator, dig holes and move dirt piles
  • Slew the crane, steer the hook and move pallets
  • Discover the shell, scaffolding, wheelbarrow and tools
Open Rotstift.ioVideo

Playable right here in the alpine world. Drive up close to the excavator or crane and press E in the glow to climb in. ESC takes you back to your parked car.
