Meet the GIMP #100: Windtunnels and Tonal Ranges
I wanted to do something special - for example an interview with Sven Neumann. But he has had no time - you’ll hear about it in the video.
But I could help out a bit with a scientific project - finding out how much a airplane wing bends in a wind tunnel. This is still work in progress, you can follow it here.
You can find the cross stitch script in the forum.
And then we have a new script out of our secret Script Writers Guild. It’s the tonal range relection script and it can do some very weird stuff. And either Bert has bugged my computer or can read minds - he included the stuff I wanted to have without having seen the video.
