Thanks to a [friendly tutorial by Codrops](http://tympanus.net/codrops/2012/08/08/circle-hover-effects-with-css-transitions/), I put together this example of CSS transitions. The buttons link to somewhat random [McSweeney’s articles](http://www.mcsweeneys.net/). In the process, I also stumbled upon the site, [Vintage Printable](http://vintageprintable.com/), which has beautiful naturalist illustrations in the public domain.
