There's a console and you can track your command! Very cool. Not sure if 3D is needed but very cool nonetheless, It might be that some things are missing (I don't know redis internals though) like some encoding step when getting data back to client, managing client connections and their state (multi, watch) etc.

Each component links to the source code, and you can open the console to enter your own commands and watch the execution flow
