For the 'image loader' fading overlay on the main image I used a small script from A Plus Design, mainly because I couldn't be bothered reinventing the wheel and writing my own. (The script can actually do much more than what I use it for. Check it out.)
I'm tracking site stats using Piwik. Piwik is a self-hosted open source tracking tool, which means that all the tracking data stays on this server, and no one but me will see it.
[I'm tracking simply out of curiosity, and to have some idea how many people actually look at this site.]
Everything else I did from scratch.
