Click the green flag to start! This is a neat little 3D crane. V0.2 can be manually operated, or run automatically. It now also can pick up and drop beams from, and onto four different tracks. It is cool. Some tricks: 1) To get it to drop a beam off, but not pick up another: Put it in a position to drop, but then tap the up arrow so that 'down' is 68 or 69, rather than 70. Then hit 'n.' You can now move the arm, and the next beam will come when down next equals 70. 2) To make them keep coming, slide pinch to zero; then, after the first beam has left, but before the next one comes, slide it to 5. 3) You can use the spacebar instead of 'n.'
