Wordle was created by me, Jonathan Feinberg. Please feel free to contact me with your thoughts.

I acknowledge my employer, IBM Research, for extending me the extraordinary privilege of using code, which I wrote on their time, for this personal project. While I did develop this web site on my own time, I developed the core algorithms for laying out and displaying words on company time.

This would have been completely impossible without the Java platform. In particular, I rely heavily on the Java2D API, the AWT Font stuff, the concurrency utils by Doug Lea, and everything Joshua Bloch has ever done! If anyone from Sun happens to see this, please write me and tell me whom I should be thanking by name.

Thank you, Martin Wattenberg, for the central idea of just throwing stuff at the screen until it fits. I raise my glass to the philosophy of "the dumbest possible thing that works."

Thank you, Frank van Ham, for explaining hierarchical bounding boxes to me. Without that notion, this would have been too slow for interactive use.

Thank you, Katherine McVety, for your expert guidance about color, and for your loving indulgence while I worked obsessively on this for two weeks.

Thank you,علیرضا فرخی, for your research and assistance in making Wordle look beautiful in Nastaliq scripts.

धन्यबाद, Eric Nedervold, for long and detailed email discussions about the rendering of Devanagari, and for giving such careful attention to the results.

Thanks, Matt McKeon for your wonderfully simple and obvious (in retrospect) solution to a vexing technical design problem.

Thanks, Jesse Kriss and Fernanda Viégas, for friendly testing and brainstorming. Fernanda, thanks especially for allowing me to completely destroy your Java plugin.

Asante, Mark Dingemanse, for your cheerful assistance in getting Wordle to speak in the extended ranges of Latin-derived alphabets.

Hvala lepa, Mitja Decman, for your interest and assistance in creating a Slovene stopword list.

Hvala vam, Marko Rakar for finding Marko Tadic and getting Croatian stopwords from him!

Dankon, Fabio Bettani, for your list of Esperanto stop words.

To Irina Ros, תודה רבה for Hebrew stop words.

Sağ olun, Mert Torun, for Turkish stop words and expertise.

Gratias tibi ago, Evan Smith, for your list of Latin stop words.

Ďakujem, Brendor, for your list of Slovak stop words.

Gràcies, Carlos Gimenez, and your students at Collegi Sant Gabriel de Viladecans, for providing Wordle with a list of Catalan stop words.

Thank you, Becky Foellmer, of Lakeview Jr. High, Downers Grove, IL. Your suggestion, concerning how to make Wordle safer for educational use, was on point.

Fonts

Most of Wordle's character derives from the high quality of its TrueType fonts. All of Wordle's fonts are created by independent typographers, and are appropriately licensed for this use.

I'm on the lookout for suitably licensed fonts with extensive international character sets. Please contact me with suggestions.

Other Software

Wordle depends on the fantastic jQuery Javascript library.

Thanks, Jonathan Neal, for your neat-as-a-pin jQuery browser detection plugin, which I use to hide irrelevant information in the troubleshooting FAQ.
