Sheds some light on the aesthetic potentials of algorithmic design, but it leaves the reader very unsatisfied. Nothing here goes beyond the basic geometric exercise level. Also, it's a short read and even shorter if you already know the logic behind the algorithms.
The "process" that Aranda/Lasch uses is also downright shallow: make an algorithmic form then force-feed program into it. I love exotic geometry if it's done thoughtfully, but the projects in Tooling are neither very exotic nor thoughtful and the end result is mediocre eye candy and so-so form driven architecture. I firmly believe that more enriching applications exist for algorithmic design; applications that are broader in scope and are guided by an intent to advance the discipline well beyond the making of funny shapes.
Philosophical differences aside, there's nothing in Tooling that can't be found on the internet, for free, and with the relevant code (See communities for GC, Processing, RhinoScript, etc). Do not pay money for this. Tooling is too hollow, too sparse, and too undercooked.
