Marnix Hamelberg, created this visualization of the Earth’s population, where population density is mapped to elevation. It presents both a familiar and unfamiliar globe, as mountain ranges are still visible, but paradoxically as flat plains.
Using census data, the New York Times posted a table of birthday distributions in the United States for people born between 1973 and 1999. The Daily Viz then turned the table into a heatmap with the colors indicating the order of the birthdays, not their likelihoods. If you look at number of births in each month, or number of births per day in each month, the results are much flatter. Still the bias towards the summer shows up.
I’m not surprised that birthdays aren’t uniformly distributed. I am a bit surprised that they’re biased towards the summer though. I would have thought that any bias that long cold nights brought, would have long disappeared with the advent of artificial lights, heat, and a move from an agrarian economy. I’d also like to see a similar charts for other countries. I suspect that if the bias is towards summer months, we’d see a six month shift in southern hemisphere nations.
It’s a simple idea. He simple creates a 9 by 9 image, and places carefully chosen pixel values to write the assembly. The “magic” is that he saves the file as raw data, and then renames it as a .com file for execution in a DOS shell. Since the file is read as a raw stream of bytes, using Photoshop in this way, isn’t any different from using a hex editor. In fact, back in The Day™ (i.e. 1992-1994) PC World would recommend using write.exe to edit different DLLs in Windows 3.1 in order to create custom menus in file manager and such. The only catch was to avoid memory alignment problems by keeping the edited string the same length as the original.
