There was no show for quite some time – and there will be a gap until the end of summer. I move back to Bremen – and that takes a lot of time and creativity away. But in Bremen I will have nearly 2 hours more time each day, because I can walk to school and don’t need to ride the famous Berlin S-Bahn Ring Line.

In the meantime I have a challenge for you! Present the place where you live to us – but look down on the sidewalk for that! The best results will be published in the GIMP Magazine #5 and of course here on the blog. The exact rules are below.

This Challenge is a perfect rip off from a challenge by Andrรฉs (Twitter) (Website), an illustrator from Buenos Aires, in the now closed forum of Tips from the Top Floor. Make a mosaik of images of the sidewalks in your city and try to transport the atmosphere.
Rolf's Example
This is my take on the Silvio-Meier-Strasse around the corner from my flat in Berlin.

The Rules

  1. Make a mosaic of at least 3×3 images.
  2. All images have to be shot straight down
  3. All images are in the same scale, use the same distance to the ground and the same focal length.
  4. All images have to be linked to each other in their theme by being from one city, one journey …..
  5. Publish your image online and post a link to it before September 1st in the comments to this blog post.
  6. License your image as CC-BY or better and allow this site and the GIMP Magazine to publish your image under CC-BY (here) or CC-BY-SA (GIMP Magazine).
  7. Rules 1 to 4 may be broken, 5, 6 and 7 have to be followed exactly.

You may download the template for my version from above or build your own one. You are free to make other forms than a square – circles or a spiral anyone?

There will be hopefully a discussion in our forum.

Episode 071: Choices

Download the Video!
Download the companion file! (…if there is one…. ๐Ÿ˜‰ )

The People of the USA are electing a new President. And we wanted to publish this Election Special some hours ahead of the schedule – but the technology was against us. Encoding problems at midnight and an alarmclock set to 0635 don’t work well together. ๐Ÿ˜‰

We wish the US (and the World) a good choice and a not so bleak future as it looks at the moment.

Philippe shows how to make the animated flag you see here.

Rolf steals a trick to enhance an image with a layer copy first converted to monochrome and then set to “value” as the layer mode.

And with the next show we’ll perhaps know who will be sitting in that nice house here in 2009. (We know it: Congratulations to Barack Obama and all the people in the USA.)
