Mar_ is a nut for it. He makes it sound like some seriously Zen shit, so that was enough to sell me on it. Check out this description:
"Let's just get this out of the way. Space Giraffe is a revelation.
I have never experienced a game previous nor after that encourages... nay, demands, you unlock your third eye as it were. Not your third eye as in you're suddenly at one with the universe and at peace with the world and your fellow man. More like how Neo learns and eventually wakes to see through the matrix, to see the code past the visual. To awake from his visual prison and see what's really going on. You think I jest? Elaborate for affect? No, I'm being dead serious. This effect is real and if you do want to finish this game you have to learn how to do it. The rewards for doing so are astonishing, or perhaps, astonishment, that what you're doing is actually happening. What others see as a mess of colour and abstract shapes randomly spewing at their eyeballs, you 'see' as a completely normal navigable landscape. 'See' in quotes because seeing is only half the reality, the other half is the audio cues that tell you what's actually going on, the code behind the matrix as it were.
It's so genius that I refuse to believe it was intentionally meant to work as effectively as it does, because I don't comprehend how that would be possible. To be able to create such a work would be to already have the gift of seeing inside of it, yet if you haven't learned to see inside it, how can you have ever had the insight in the first place? It's the whole chicken and egg routine.
Regardless, Jeff Minter is surely a design genius and as mad as a balloon."
