#42, the current version runs in any mobile browser that supports Canvas, which the majority do now. Performance isn't great though, but since it's open source there's nothing stopping somebody from making a native app with mumble listening built-in. And I like the icon idea a lot.
#43, it started from me playing around with HTML5 and SourceMod, based on stuff jimbomcb had done. When I got to doing the HUD I based it off omp's TFTV branch and thought, "This would actually be neat for casters to have during matches"
Went to Lange about it and he liked it, so I got to work. Sal saw a screenshot in another thread and gave birth to the idea of a shrunken, no-HUD version which could be brought up on stream as a minimap or overview.
