The following software is freely available and still works at the time of this writing but is unsupported and not actively maintained by me. For years I kept meaning to set aside time, but it didn't happen and the chances are not improving. Do not expect any updates.
Most of the source code is available. Take what you want and do something great with it.
The Shortcut Recorder project is still run by the Shortcut Recorder community.
Plugs into Google Notifier to output Growl notifications instead of its own version.
Did you know: Previously known as Google+Growl and Gmail+Growl. The first plugin into Gmail Notifier for Mac.
Broken: Could handle calendar notifications better.

A color picker plugin for the Mac OS X color panel to read out hexadecimal colors.
Broken: Despite numerous tries to figure out the right thing to do to handle calibrated colors, I could never get it to do the right thing. Also, sandboxed apps makes it unable to read global settings, which means it forgets about having asked about updates - you can download this special version that has checking for updates disabled.
Alternatives: Developer Color Picker does more in a slightly less crystal clear package. And in OS X El Capitan (10.11), there is finally a field for the hex color code in the color sliders tab (the second tab) of the color panel, if you select RGB in the list.

Create services for Mac OS X.
Did you know: Created at the request of John Gruber, well-known Daring-this-or-the-other.
Slightly broken text.

Search the web from the menu bar.
Broken: Uses a Google search API that has been deprecated and not replaced with anything approaching useful. The search engine discovery is apparently moody and doesn't deal well with ajaxified sites (where the search happens without "jumping to another page"). Update in 2015: Even more broken on El Capitan.
Alternatives: Swing a cat in the Mac App Store (I have heard things about something called Alfred) or search from the location bar of your browser. Spotlight in Yosemite and later could also possibly handle things.

Source code is now available. It's a mess. There's a rewrite that never went anywhere because of the Google API problems.
Quick hack to generate random messages by scraping the chat logs kept by Adium and feeding your messages through a Markov chain generator (tech for "finds out which words are mostly commonly used in sequence and is able to use that to build new sequences that look quasi-plausible").
Broken: Terribly, I assume. It's a quick hack.

All of the above software was written by me, Jesper, from 2005 to about 2013. I did it for fun. Thanks for the kind messages, the donations, the discussions about features and ideas and interfaces and needs. I'm sorry I couldn't do it well enough and for long enough. I hope you're still happy with what you got.
So long, and thanks for all the fish.
