FCharts SE is a free stock charting program which will import price data from a wide range of sources, displaying it as OHLC, Candlestick and Line charts. It has a number of built-in indicators (MACD, RSI, Exponential and Standard Moving Averages), or you can write your own with the inbuilt formula language and display them as standalone charts or overlays. You can draw trend lines with a few clicks of the mouse and print your charts in full colour or black and white.

yGen is a combination text editor and compiler, generating finished files (be they html, text, php or any extension you like) from template files and includes. Includes can be nested, allowing you to build complex files from duplicated parts - without manually duplicating anything.
yPlay is an MP3 player with multiple playlists and a clean interface. I find too many music players have tiny, ambiguous controls and overly complicated menu structures. I'm only interested in how quickly I can find and play a particular track or set of favourite songs.
