Tree is a recursive directory listing command that produces a depth indented listing of files, which is colorized ala dircolors if the LS_COLORS environment variable is set and output is to tty.

w3m is a text-based World Wide Web browser with IPv6 support. It features excellent support for tables and frames. It can be used as a standalone file pager, too.

BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides minimalist replacements for the most common utilities you would usually find on your desktop system (i.e., ls, cp, mv, mount, tar, etc.). The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts.

Cntlm is a fast and efficient NTLM proxy, with support for TCP/IP tunneling, authenticated connection caching, ACLs, proper daemon logging and behaviour and much more. It has up to ten times faster responses than similar NTLM proxies, while using by orders or magnitude less RAM and CPU. Manual page contains detailed information.

LÖVE was created to be a user-friendly engine in which simple (or complicated) games could be made without having extensive knowledge of system or graphics functions and without having to dedicate time towards developing the same engine features time and time again.

Plymouth provides a boot-time I/O multiplexing framework - the most obvious use for which is to provide an attractive graphical animation in place of the text messages that normally get shown during boot. (The messages are instead redirected to a logfile for later viewing.) However, in event-driven boot systems Plymouth can also usefully handle user interaction such as password prompts for encrypted file systems.
