I knew I've read about this before! Patrick Dunn gives some modern rituals for creating images with synthemata and then animating them in his The Practical Art of Divine Magic, based on the same neoplatonic and hermetic texts you mentioned. For more info see Exercise 3.1 Creating an Image (pp 101-103) and exercise 4.4 Ritual for the Animation of a Statue (pp 166-172) in the aforementioned text.
