GNOME floating background project subtly changes the color of the GNOME desktop over time -- so slowly that it wont be noticed. This is a good alternative to placing a wallpaper.

The program does have a minimal processor time consumption, as it
sleeps most of the time and its computations are not complicated. In
fact, GFloatbg doesnt change the color directly. It relies on
Nautilus (or an equivalent application) to paint the background using
the color set in the gconf key
/desktop/gnome/background/primary_color, which this program updates
periodically.

GFloatbg doesnt use any window, button or menu, and it can only be
stopped by killing it. This is a feature I dont like too much, but
making a realy nice user interface is just too much for such a little
joke...

GFloatbg starts with a random color and changes it deterministicly by
moving through a HSV-model of colors.

In the HSV-model, colors are described by three parameters:

h = hue stands for the tint of a color
(0 degrees is red, 60 = yellow, 120 = green, 180 = aquamarine, etc)
s = saturations stands for the brightness of the color
(0 = white, 1 = bright)
v = value stands for the intensity of the color
(0 = black, 1 = normal)

Every 10 seconds the hue is increased by 1 degree and the saturation
is changed by a sinus over the hue. The value remains fixed. The
default values are chosen such that all pastel tints are visited, but
these can of course be customized:

Usage: gfloatbg [options]
where options are:
-help
-value < float> (default 0.87)
-satmid < float> (default 0.375)
-satvar < float> (default 0.125)
-fase < float> (default 0.25)
value, (satmid-satvar) and (satmid+satvar) must be between 0 and 1

PersonalDB is background process that provides access for multiple users to individual SQL databases. The SQL database provides a central internet accessible datastore for a variety of applications. In particular, the database can be used as a personal information manager (PIM).

However, SQL databases are simply a way of storing structured data. As such, a PersonalDB account can be used to store many different types of data. A PersonalDB account is an ideal way of storing information that should be accessible world-wide.

Personal data like addresses, todo items, and memos are certainly are good choice. A PersonalDB account can also be used to store application settings, so that they follow you from computer to computer.

Nitrogen project is a background browser and setter for X.

It is written in C++ using the gtkmm toolkit. It can be used in two modes: browser and recall. It is multi-head friendly and can even work in GNOME. Nitrogen has been in development for over 2 years, due to real life and laziness. For more info, check out the features section.

All I did was move some elements around to compensate for the background.

DansTuner project is a program that tells you if you are playing a pitch in tune.
Major features include automatic discovery of which note you are trying to play (good for trumpet, singer, etc.), the ability to play a guide tone at a configurable volume, a graphical moving "needle" with a red/green display and detail about how flat or sharp you are, and an easily configurable background noise threshold.
Main features:
- takes audio from the default device
- if it is above a background noise level, detects the pitch
- takes the difference between that pitch and an "ideal" (equal-tempered) pitch, and shows you that difference
- plays a guide tone along with you to help you tune
