Rigging a Carnivorous Plant is probably not the thing you need to do all the time, but of course you can use the same approach to built any other character rigs. One special thing about the IK expression that we are using is, that it supports 'arms' with 3 instead of 2 segments. Normal arms consist of upper and lower arm, but fingers, for example, consist of three segments. So the approach shown here, is also very useful for hand rigs.
