There is a similar guide to hangul with information arranged in the shape of the periodic table of elements, the "periodic table of hangul": http://www.aboutletters.com/pfaq.html. I found it to be a reasonably handy reference that logically compiles all the information in one image as opposed to this guide's gradual introduction of vowels and consonants mixed in batches.

The author no longer authorizes distribution of the image over the internet, however copies can be found with a google search.
