Languages of the future will be compiled to CSS in the same way that languages of the present are compiled to Javascript. I get shivers just thinking about all the fun I can have breaking web semantics this way.

CSS is already turing complete: - http://stackoverflow.com/questions/2497146/is-css-turing-complete http://stackoverflow.com/questions/2497146/is-css-turing-com... This project doesn't use rule 110, it uses LESS which sorts out the logic while compiling and spits out the results in css.

  I still say that doesn't count as long as you have to make the user click on all the cells. CSS by itself is capable of doing a single row of rule 110, but that's not enough.

haha, thats a funny thought. I like CSS. I would love for it to have variables so I could consolidate changes and edit them via JS. Sorta like all the CSS-libraries. o.o am i doing it??

  I highly recommend checking out LESS -- even if you ignore all of it's features, being able to define variables alone is worth it :)

    Yes i have been meaning too

  CSS does have variables: http://www.w3.org/TR/css-variables/ http://www.w3.org/TR/css-variables/ Of course, this being the web you’re somewhat limited in browser support: http://caniuse.com/#feat=css-variables http://caniuse.com/#feat=css-variables

It's not really any surprise that templates (or CSS) could be Turing complete, as all the lambda() function does is the same thing a template does - replacing the macros in a template with an argument. This is actually an important lesson that is often missed: if the app you're writing gives the anonymous users any kind of find/replace macro capability, you're giving them a fully Turing complete language (though it's probably not easy, but that rarely stops anyone) and all the potential problems that can bring.
