This is a cool project idea. My first impression is that this feels like a natural fit for GWT. The ImageBundle mechanism would allow you to automatically build css sprites at compile-time -- and the logic for accessing the individual tiles from the sprites: (The gwt-canvas project is a small wrapper that would allow you to draw instances of the Image class to the canvas. http://code.google.com/p/gwt-canvas/ http://code.google.com/p/gwt-canvas/ ) It would also make it easier to move larger chunks of the FreeCiv client into the browser in a manner that would be easier to refactor and maintain than Javascript - and while being compiled to be as small as possible. Java, for all its faults, is strong in refactorability, which would be essential for keeping the code in sync with a moving target like the current C implementation.
