A big yes to the whiskey stone. I have a couple of large metallic spheres and they work great to cool down the espresso + milk (cold milk, no froth)

This is one of the reasons why working out in VR with games such as Beatsaber and Ragnarock impacted my health quite positively. Workout is no longer an inner battle trying to fight myself, but a very enjoyable hour of my day(but it’s important to move ASAP to both games’ higher difficulties!). Have been doing it for almost two years and it doesn’t get old. I’m also quite musical, so that might have a lot to do with the enjoyment.

Pretty cool! Reminds me of the Alpakka controller experiment, which uses a conventional PCB but has a conductive plate used to trigger the gyros (similar to the steam controller, but this one has dual gyros, which allow for insane stability and accuracy). Video here and documentation here
