I really like the animated demo graphic you have in the imac. Can i ask how you made that?
The process for creating the images is as follows:
Use quicktime to take a video, called demo.mov (or equivalent movie capture program with whatever file format)
Create a color palette from the movie $ ffmpeg -i demo.mov -vf fps=10,scale=1378:-1:flags=lanczos,palettegen palette.png
Create a gif from the movie using the color palette $ ffmpeg -i demo.mov -i palette.png -filter_complex "fps=10,scale=1378:-1:flags=lanczos[x];[x][1:v]paletteuse" output.gif
Create a sequence of pngs from the gif $ convert -dispose Background -coalesce output.gif -colors 256 PNG8:target-%d.png
party!
