This week I show you how to simulate a Graduated Neutral Density Filter with GIMP. This was started by a thread in the forum. And as I now need more time between recording and publishing, the thread has grown considerably and Bert has already made a script for this. So check it out in the forum!
While trying to create a filter for the image I stole from Bert I tell you a bit about the Blend Tool and give (again) an introduction into layer masks. “White reveals and black conceals!” 
If you are a Linux Geek living in the UK, you may be tempted to attend the Ogg Camp, organized by the Ubuntu UK Podcast and Linux Outlaws.

You challenged Philippe to make a bill of a currency from scratch. It is a lot more complicated than it looks at the first glance – of course – otherwise I would print some Euro notes at the beginning of the week instead of going into the school for earning my pay.
Bills have a complicated background for discouraging counterfeiters. Philippe analyses the background of a 10 SFR bill from his home country and then combines two images from an analysis of Linux filesystems to the intricate pattern on the right.
The foreground of the note will be finished in his next show.
