nautilus-follow-symlink is a nautilus extension that adds a context menu entry to nautilus on symbolic links pointing to directories, which once clicked opens the pointed directory (the real path) in a window.

Video Contact Sheet *NIX creates a contact sheet (preview) from videos by taking still captures distributed over the length of the video. The output image contains useful information on the video such as codecs, file size, screen size, frame rate, and length. It requires MPlayer or FFmpeg and ImageMagick. It is confirmed to work on Linux and FreeBSD, and possibly other POSIX/UNIX systems.
mp3plot creates a plot (textual or graphical) of the bitrate distribution of an MP3 file. It displays which proportion of the audio file uses each of the possible bitrates. The plot can serve, for example, to compare an audio source as encoded by different encoders or settings or to display how the chosen (average) bitrate was achieved by the encoder.
