Move the mouse to bend the 3 bright arms. Overlap each with its corresponding color of stationary, darker arm, so that the threads between joints are hidden. Done successfully, you'll see a heart made of water, and then be presented with a random new goal.
Every generated target is possible. If it seems like the joints can come close, but not quite meet, the solution may be quite far away. Try jumping the cursor elsewhere, then retrying the finer approach.
This is a free web port of my iPhone/iPad app feelforit, which was a finalist in IndieCade 2010.
If you like this, you may also enjoy some of my other apps that I have recently liberated from iOS exclusivity: Transcend and Tumult HD. Both are available here on Newgrounds - search or browse my profile.
