And because matcap is based on an old Normal mapping technique I decided to make a material that can use specific matcap depending on the object's random number or by assigning specific index.
For this I made a screenshot of the matcaps preview panel and edited it slightly in Gimp. Then using the power of material nodes and some math it turned out like this.
From here you can amaze your unsuspecting friends by making multi-matcap candy ball.
Do you think this texture tiling deserves a tutorial?
Let me know!
