I've been experimenting with #otk and #PicoGL. I'm trying to see if otk can use PicoGL as a back end in place of a full-fledged #OpenGL implementation. If it works, the otk #GUI library could be used on machines that don't support OpenGL or Mesa including #embedded systems that use #NanoX.

Another disadvantage of #propietary software: you can't freely reuse non-commercial code from the 80's and 90's. You want MGR instead of X11 for legacy 486 machines? You can't. Either you get #9front and Rio, or forget about retrifitting it for Unix clone. #nanox OTOH can be shared under MPL terms.

Also it works on ELKS, the PSP, under SDL, framebuffer and lots more.

I’m in the garage on a rainy day prepping my #ARRI #AMIRA for my first NFL Films shoot of the season. I’ve got Commanders @ Jets on Saturday. It’s the first shoot with my new #CoreSWX #nanoX batteries. #VideoNerd
