One nice thing about having access to a big printer is that I can think "I want more colorful posters" one day, and put these up on the office wall the next day.

@iliana @federicomena See https://github.com/ilianaw/html5nyancat or https://aschmitz.org/output/posters/nyan_posters.svg , but I wouldn't use them in a test suite: there have been copyright claims in the past.
