Alright, so after trying all available demos, I kinda made the weird call to make Harmonix VR my first VR purchase. There are several other games I am really interested in, but for now I would just like to focus on this, as I read some reviews before I bought it and most people are trashing it to hell and back.
The easel mode is genuinely awesome and the best VR feeling I have encountered so far. Its a 3D drawing application with the strokes reacting to the music. To get the bad out of the way: The rest of Harmonix VR is kinda... pointless, which is also the reason why most reviews turned out so incredibly negative. Most of the other stuff is actually pretty shitty, so I will likely never do much in those modes, but I came back to that 3D drawing again and again and again. Drawing around me feels so much more vivid in VR than any of the other VR experiences managed to be so far. Its still a bit janky and probably overpriced for what it is, but omg do I love this ... lets call it application instead of game.
This is making me want Dreams VR sooooo much. If you are a creative type and you like doodling around with different brushes and whatnot, definitely try the Harmonix VR demo. Unfortunately, you will need to finish the pointless first level first, but in the Easel mode, you can already check if this is something for you or not.
I made some screenshots to share, but keep in mind that its of course not even remotely as interesting to look at them as screenshots (and drawing them yourself is even better). I usually tend to load up my playlist with stuff from the USB stick and draw something that the first random song inspires me to.
I really wish Harmonix would continue to expand on this, as this is genuinely the only "game" so far that drags me out of reality into this little VR world that I interact with.
