Prototype 4: SPC

Drag a few parameters and watch procedural architecture take the floor.

Prototype 4: SPC is a compact 2017 architecture generator that turns parameter dragging into a shifting spatial sketch. Its itch.io page pairs a browser player with simple mouse-and-keyboard directions, while the creator's portfolio places it inside a semester of rapid weekly experiments.

What is Prototype 4: SPC?

SPC treats architecture less like a blueprint and more like a set of knobs waiting to be nudged. The project page asks you to drag parameters with the mouse, then use W, A, S, and D to look around the generated space. That narrow setup is the point: this is labeled a prototype, not a construction game with missions or a finished design suite. Laurenz Riklin made it in 2017 for NYU Game Center's Prototype Studio, where the larger assignment was to finish a small playable idea each week. Here, the prompt was to make a game from box art, and the result became a tiny machine for coaxing rooms and forms out of rules.

What you can do there

  • Drag parameters to generate architectural spaces
  • Look around with W, A, S, and D

Why we picked it

The attraction is the unusually direct bargain: adjust abstract parameters and get architecture back. SPC turns procedural generation into something closer to a desk toy, with enough structure to invite curiosity and little enough ceremony to keep the experiment in charge.

How to get the most from it

Open it on a desktop, enter the browser player, and start by changing one parameter at a time so you can see what each control contributes. Use W, A, S, and D to change your view, then switch to fullscreen if the embedded frame feels cramped.

Good to know

This is explicitly a 2017 prototype, so arrive for a focused experiment rather than a polished building game. The published controls are mouse plus W, A, S, and D, and the creator recommends fullscreen. The page also offers macOS and Windows downloads through a name-your-own-price flow.

Who made it, and when?

Laurenz Riklin is the credited creator or organization. The earliest supported launch date we found is 2017.
