I think I may have shared this image here before, it is "The Impossible Triangle" originally created by Penrose, he was an avid fan of Escher's work and created the original concept.
Well now I would like to introduce you to "The Impossible Star" in full colour :)
The Star image reminds me of the song, "Weave" by Rosemary Crow
Chorus: Weave, weave, weave us together,
Weave us together in unity and love.
Weave, weave, weave us together,
Weave us together, together in love.
We are many textures, we are many colours,
Each one different from the other.
But we are entwined with one another
In one great tapestry.
We are different instruments playing our own melodies,
Each one tuning to a different key.
But we are all playing in harmony,
In one great symphony.
A moment ago, still we did not know
Our unity only diversity.
Now the Spirit in me greets the Spirit in thee
In one great family.
