The six rooms
Thirty pieces, arranged by the environment and the era rather than by the idea. Each room opens on its own page; the archive lists every piece in one place.

Room 1
Green Screens
The first rooms where editor, compiler and debugger shared one window — Smalltalk-80, Emacs, vi, and the machines they ran on.
4 pieces
Room 2
The Blue Box
Turbo Pascal, Turbo C, and the Borland decade — forty-nine dollars and the compiler that stayed resident in RAM.
5 pieces
Room 3
Form Designers
When the form became the program — Visual Basic's toolbox, Delphi's component palette, and what the visual designer changed about who could build software.
4 pieces
Room 4
The Inventions
Ideas that had to be named before they could be built — syntax highlighting, the breakpoint, IntelliSense, refactoring, the Language Server Protocol.
7 pieces
Room 5
The Builders
The people behind the tools — Hejlsberg, Stallman, Joy, Moolenaar, Kay, Ingalls, Gamma, Fowler, Beck, Dmitriev.
5 pieces
Room 6
On the Shelf
The later environments and the institutions behind them — Eclipse Foundation, JetBrains, GitHub and Atom, Visual Studio Code, JupyterLab, the licences they shipped under.
