Room OS
Room OS (2015) was our first spatial computing environment.
It grew out of making the Research gallery (2015), a poster of group projects that could be lasered to bring up details.
The first "Hello world"-like application in the system was Bouncy balls (2015).
Tile files (2015) was an early idea for spatializing the programs themselves.
The past is always with us (2015) displayed the room's view of itself.
In the Dynamic Library (2015), we could laser-browse through books.
The urge to improve the library led to our second spatial computing environment, Hypercard in the World (2015), and development continued from there.
