“BLUE…. The colour of serenity and healing.” This is the greatest thing ever (as linked in this comment thread). Nature Treks is “a non competitive, interactive experience aimed as an aid for relaxation and healing”. It’s built in Unity using
pretty much stock assets all original assets, with swishy nu-age music. Basically it’s about having a wander about in an alarmingly bloomy meadow/pond area while collecting particle effects. “VIOLET…. the colour of transformation. It can help with sleep and stress.” That’s good stuff. And no enemies of any kind have to be dispatched with a shotgun blast or physics violence. It’ll help with that problem you have with your soul. You know, with the inky discharge of evil.
Anyway: relaxing and informative! Turquoise is the colour of intuition, apparently. Gotta get me some turquoise for good times. Also: purest green. (For a less trite experience with wandering around in a musical woodland, try Proteus.)
