FFmpeg chromakey filter / Filthy Frank

Colour keying was available in FFmpeg since 2.8, but a 'chromakey' filter was included with the recent release of version 3.0. https://twitter.com/oioiiooixiii/status/704052912687878144

After ITAR-TASS reporter Андрей Ситов (Andrei Sitov) congratulated them on their work, and asked about any involvement with Russia, the science folks scrambled around like someone just threw a stink bomb on stage #BooRussia

The LIGO people were also very touchy when asked about how quickly they happened upon the results. It reminds me of that story about how it took Australian scientists 17 years to discover "alien" radio signals were caused by a dodgy microwave oven in the kitchen.¹



Incidentally: Rip Torn, I mean Kip Thorne, has a particular verbal tic, reminiscent of Ali G - "gravitational waves... Ayyyy".

EvilSpeak

alias evilspeak="cat /dev/urandom \
| espeak -s 60 --stdout \
| ffplay - -af aformat=channel_layouts=1c,asetrate=16000,aecho=0.8:0.9:1052"

The alias name comes from a play on the name of the command "espeak", as well as the title of a 1981 film, starring Clint Howard, a bullied military student who begins to communicate with a demonic entity, through a computer (Apple II).
