Anyone who has hand-coded HTML (I know, oldskool) has wished for a tool like this real-time HTML editor, though regrettably the days of hardcore hand-coding HTML are pretty much over. I still code HTML in my free time just for the tactile feel of simple code beneath my fingers and remembering the old day before things got easy. Real-time HTML Editor puts your code into practice as soon as (and somewhat before) you type it. Through the power of AJAX, HTML is now more fun. This tool is obviously not for serious coding, but it can help a noob learn the basics or help you text a small script, such as a MySpace layout or something nonsensical like that. I checked it out for the nostalgic value more than anything, so if that is your brand of suck tape, give it a whirl.

Mais proof of concept que outra coisa. Mania dos produtos de limpeza agora :P
