Introducing a new project of mine: Tiewrap is a game engine not unlike LÖVE designed to be small and efficient, but with Duktape as a scripting language. Of course, it's similar to Legimet's Duktape-nspire project and heavily inspired from it, but this one uses SDL and should work on a variety of platforms, be it Windows, Mac, Linux, Nspire, or whatever SDL has been ported on. Planned features include a module based on the HTML5 Canvas API.Right now it doesn't do a lot, but you can check it out ...

Of course, this means sometimes you have to use parenthesis in RPN expression ('sacrilege,' RPN enthusiasts cry), but it's generally a lot more convenient than any one input method. Screenshots[/...
