I'm spending time digging into little games on itch.io at the moment so I thought I'd share a few with you. This one is Morphê [official site] by Pixelfoot Games and it fits into that art game/musical desktop toy category, if you're looking to get a sense of what it is.
You're on a little island which sort of doubles as an art park with a tiny pond and trees and obelisks you can play around with in order to change the soundscape of the space. I was pottering and doing that, but then I paused to take a screenshot or four of the lake. In standing still I found that when you do the game gradually blurs until what you're seeing is an ambient visualisation to accompany the music.
For me that moment was really lovely - it's kind of like you're seeing the game having a daydream.
Morphê is pay what you want on itch.io for Windows and Mac
