Animation Nodes

Allows you to: Animate almost anything in Blender! This addon brings parametric modelling and animation to life! I've been wanting a feature much like Houdini where you can input node values and have them drive object properties. By default, this is possible through Blender via constraints and python coding--but this addon makes it intuitive and easy to use. It makes it easy to do mechanical rigs, motion design, and programming. It opens up a whole array of possibilities!

BLAM Blender Camera Calibration Toolkit

Easily match the angle and perspective of a reference photo. This addon makes combining a render with a photograph of a piece of cake. Using some clever programming, it accurately guesses the focal length and angle that the photo was taken with, so you can effortlessly put a render over the top :) We mentioned it one of our recent tutorials.
