You can do encapsulations and "caviars" and stuff in ways that are pointless, and a lot of coattail-following stunt cooks do that. But when Achatz or Dufresne decide to do something, there's usually a very well-thought-out reason for it.

I use my circulator and my pressure cooker on a regular basis and play with the siphon from time to time.
In the ingredients department, I picked up a variety of thickeners etc. to experiment with but, to be honest, I haven't done a lot with them.
There are some good ideas and techniques in books like Modernist Cuisine at Home. There are also instructions for making an omelet that would probably take hours. I won't be doing that.
