Kong Automatic UI Hider can fade out pieces of the user interface (Minimap, PlayerFrame, Recount, etc.) and then automatically show them again when moused-over, entering combat, or any of several other user-specified conditions are met.
Type /Kong in game to access the config GUI. Kong can automatically fade things in and out based on things like:
Unit in Combat
Unit in Vehicle
Unit Health Level
Unit Power Level (Mana, Rage, Focus, etc)
Unit is Casting
Unit is Moving and Unit Speed
Unit is Mounted
Unit is Resting
Unit Exists (You have a target, focus, etc)
Unit is Unit (Player is Target of Target, etc)
Instance Type (Dungeon, Raid, Battleground, Arena, or None)
And also any macro condition:

[bonusbar:5] — The possess bar is active (controlling a vehicle or another player)
[channeling:<spell name>] — Channeling the given spell

[dead] — Target is dead

[flying] — Mounted or in flight form AND in the air
[group: party/raid] — You are in the given type of group
[harm] — Can cast harmful spells on the target
[help] — Can cast helpful spells on the target
[indoors] — Self explanatory
[modifier:shift/ctrl/alt] or [mod:shift/ctrl/alt] — Holding the given key
[mounted] — Self explanatory
[outdoors] — Self explanatory
[party] — Target is in your party
[pet:<pet name or type>] — The given pet is out
[raid] — Target is in your raid/party
[spec:1/2] — Currently active talents

[stealth] — Stealthed
[swimming] — Self explanatory
[unithasvehicleui] — Target is in a vehicle
[vehicleui] — You are in a vehicle
All conditions can be negated by preceding them with "no" (e.g. [nogroup:raid] will show a UI element when you are not in a raid). More information on macro syntax can be found here.
Hold shift while clicking in the config GUI to select and configure multiple frames simultaneously.
Use the mouse wheel to uncover overlapped windows in the config GUI.
Setting the Hidden Alpha of the Minimap to 1% will allow quest and other tracking icons to remain visible while the Minimap is faded out.
Kong supports multiple profiles via the command line. Type /Kong profile in-game for more info.
