280North bring Keynote to the web

I’ve first seen a preview of this at the first JavaScript developer meetup in San Francisco earlier this year, but now the 280 North guys have released their very Keynote-esque presentation editor for the web.

Have a play with it and especially check the key-commands and drag and drop support. The shape designer is also pretty nifty. That said, I am on a hefty MacBook pro, so I’ll check the performance on the old work-horse Thinkpad at home later.

The most amazing thing about this is happening under the hood: the developer wrote a library that abstracts browser rendering engines using Canvas, SVG and Flash (on a per-need basis) into a unified language – Objective J which is – as the name suggests – a mapping from Objective C to JavaScript.

I tried to milk them for more information when we met briefly (yes, the guys involved did work at Apple before – obvious, isn’t it), and will try to cover this interesting concept in more detail soon on Ajaxian or YDN.
