This map is for practicing the mineral boosting trick I introduced. See the following thread if you do not know this technique: http://www.teamliquid.net/forum/viewmessage.php?topic_id=152345
The map features: 1) Tracks your % of successful mineral boosts in the top left 2) Timer in the top right 3) Type "-r" to reset the map and "-v" to end the map 4) Missed boosts causes workers to glow red and show "Miss!"
There are still some bugs, but it is good enough for practicing this trick.
