iOS Pick: Knots 3D

Alex Lindsay's pick of the week on MacBreak Weekly 490 is Knots 3D by Nynix. This animates the process of tying and untying more than 100 knots. As you scroll and drag back and forth with your finger, you can see exactly how each knot is made. If you're interested in how to make knots, this will teach you in a very visual and interactive way.
