It's usually low impact on the knees & backs of perrenial beginners like me. If I'm stationary cycling, I can sneak in my favorite entertainment to make the time fly by.
OpenAL is a cross-platform 3D audio API appropriate for use with gaming applications and many other types of audio applications. The library models a collection of audio sources moving in a 3D space that are heard by a single listener somewhere in that space. The basic OpenAL objects are a Listener, a Source, and a Buffer. There can be a large number of Buffers, which contain audio data. Each buffer can be attached to one or more Sources, which represent points in 3D space which are emitting audio. There is always one Listener object (per audio context), which represents the position where the sources are heard -- rendering is done from the perspective of the Listener.
Tin Can is a space survival simulator, where you are trapped in an escape pod after the loss of your ship. There are a few systems in your escape pod, and each system has components you need to look after. Your pod regularly flies through astoroid fields & other space phenomena that break these component parts forcing you to repair, replace or do without the systems keeping you afloat.
It's a word-puzzle game that incrementally teaches you how to use Regular Expressions (RegEx) to find & replace text. Some of the puzzles add silly restraints for you to work around, and the game has charming NPC coworkers that introduce each challenge.
