It's a machine my brother built out of old parts and is called the "Wish Fulfilling Machine". It is installed outside of his house and is a favourite spot for hikers and schoolkids - you can press all sorts of buttons, pull levers and connect cables to make stuff happen, there's small screens, gauges, a fan and other moving parts and displays. He has now made this online version.

It's my favourite machine ever and I believe it really works! Here's a translation of the instructions:

Instructions for use: Congratulations on using this wish-fulfilling machine! Make a wish whilst lovingly operating the machine according to your own ideas. If you treat the machine, the universe and all its creatures with enough love, your wish will come true. You cannot operate the machine incorrectly as long as you treat it and the rest of creation with kindness.
