Ray Cromwell has just released a beta version of their open source GWT charting and visualization platform, Chronoscope. Although I don’t see anything currently there at the moment, it’s supposedly being used in Timepedia, a collaborative time-oriented search engine. You can check out Ray’s blog post for more detail on Chronoscope’s capabilities.

So I finally started to work on a just for fun GWT project, and the result is GSudokr, a free Sudoku game. The project allowed me to play with a lot of interesting GWT features that I hadn’t worked with before, including Internationalization, History, and a whole slew of new widgets provided by the MyGWT library. I did spend a little time trying to choose between MyGWT and , libraries which both offer similar widgets sets. GWT-Ext seems to have slightly more community support, judging by its forum activity, but in the end I went with MyGWT because it offered a nice SWT-like API which I was familiar with. After using it on this project, I think it was a good choice.

I wrote a post a couple of months highlighting a simple GWT based game called PlayPlate that was written by Giancarlo Todone. He created the game to demonstrate the features of his GWT Animation Kit that he was working on. Well, good news, because the library is now publically available to play with. Take a look at on the GWT developer forum for more information and download links. I don’t currently see an online demo to play with, but it looks like there are some examples you can download yourself.
