Is there a command/program for OS X that allows me to hook to a file and display its changes in realtime without re-opening it, much like "top" monitors system processes in realtime?

You can use

to monitor single log file.If file is deleted, then created again you may want to use
tail -F
to actively monitor file changesIf same file is being appended too use
tail -f
