This is why I love HN. Were you randomly looking up Valve-assigned patents and happened to stumble on this?
Thank you... same here!
I'm just very interested in the game industry (and a lot of other fields). I tend to R&R (Read and Research) a lot!

Edit: Valve Corporation patents, for those interested:

From 2012: http://kotaku.com/5890372/is-this-valves-control-pad-design/
This stuff happens all the time. Why is R this way? CEO of R Inc. comes up to tell you. Why is S not in space? It just so happen that a engineer from the space program is reading the comment and answers with a detailed insightful post.
When that happens, HN is awesome.
