All Berlin Streets, ehm, visualized

Ok, this is probably the cheapest visualization I ever created, but since Ben Fry has done the same before, I think I’m allowed to do so, too. This map simply shows all streets and railroads of Berlin. Likewise as in the US version, one can identify relevant geographic features like parks, rivers and lakes at places without streets.

Thanks to the kind folks at OpenStreetMaps and cloudmade.com, creating this image took me five minutes, literally. Three minutes for downloading the Illustrator document and two for a little editing. Well, I not even dare to put my name on the map..

Creating the same map for Germany would be a little harder due to the increased amount of data. But to really keep up with the US version by Ben Fry the ultimate goal should be to render a street-only map of entire Europe. Kind of a challenge, isn’t it?

And, just in case you want to hang this map upon your wall (like me), here are 150dpi (11mb) and 300dpi (27mb) versions which you can use to print the poster at your favourite poster printing service. Continue reading

Generating Color Blindness Test Images with Processing

My wife recently observed my two-year-old son eating green strawberries and is now curious if he has some kind of red-green color blindness. Unfortunately, he is not yet able to give us the name of numbers, so the commonly used Ishihara test images won’t do. Well, I thought it´s a nice idea for this rainy Sunday afternoon to generate some of those images myself. Instead of numbers I used simple images of things I knew my son is able to name. If you like, find the source files here. The icons are taken from thenounproject.
