At least for me, this was just an interesting curiosity. I have jumped so far into the deep end with so many other crafts that I do not intend to go that route with painting. I have also bought so much paint, including several sets of Geneva paint, that I can't see the day I will need more.
But what is interesting in this video is that Conor makes paint about as fast as you can mix a color. He calls it 20 seconds. All there is to it is to deposit a small pile of pigment powder on the palette, a few drops of oil, and mix with a palette knife. He says that works today because the pigments one can buy in bottles are twice as fine as the finest pre-industrial pigments, and therefore one does not need a lot of expensive gear or elbow grease.
Check it out if this kind of thing interests you, and you didn't see the video when it came out a year ago.
