wmii logo
Posted on 2008-03-09.

Mousing around on my laptop is quite tiring, so I've been running the wmii tiling window manager on with the wmiirc-lua replacement event loop instead of Gnome for a few weeks now.

Fixed Layout Example
Posted on 2007-10-02, last modified 2007-10-03.

I recently put together a page with some wedding photos and I wanted to create something a little different than the standard web photo galleries you can find everywhere. I decided to lay out the thumbnails overlapping and clustered on the page, based on their subjects.

My first thought was to mock-up the page using Inkscape then copy and paste coordinates and sizes from its interface. Fortunately Inkscape's file format is dead-simple and all I had to do was write a little script and I could generate HTML and thumbnails straight from my Inkscape layout.
