I sure hope so.

Isn't that what they came up with after 'Claymation'?

Did you mean Racemization?
Here is a link..

Racemation \Rac`e*ma"tion\ (r[a^]s`[-e]*m[=a]"sh[u^]n), n. [L.
racematio a gleaning, fr. racemari to glean, racemus a
cluster of grapes. See Raceme.]
1. A cluster or bunch, as of grapes. --Sir T. Browne.
2. Cultivation or gathering of clusters of grapes. [R.] --Bp.

Racemation Meaning and Definition: :D
(n.) Cultivation or gathering of clusters of grapes.
(n.) A cluster or bunch, as of grapes.
why do you want to know? if you don't mind me asking... are we gana make wine?:) lol

It also has to do with the turning of light. Controlling the substance that light is made of seems (to me) to be akin to the ultimate tool.

"the turning of light" does not exist except in a black-hole (unless your talking about turning light BULBS... or the science involved in potencial informational time travel)
ultimate tool for what?

Cakes, really, are you ever going to READ and see that you have the wrong word? it is NOT racemation that you want to know about but
Racemization!!! like greenflame says!
From Wikipedia, the free encyclopedia.

In chemistry racemization refers to partial conversion of one enantiomer into another.
Chiral molecules have two forms (at each point of asymmetry) which differ in their optical characteristics: the levorotatory form (the (-)-form) will rotate the plane of polarization of a beam of light to the left, while the dextrorotatory form (the (+)-form) will rotate the plane of polarization of a beam of light to the right. The two forms, which are non-superimposable mirror-images, are said to be enantiomorphic: each is the enantiomer of the other.
Many chemical processes take place without regard to a substance's optical characteristics, and result in a racemic mixture in which neither form predominates. However, pure forms of the enantiomers can be obtained: for example, by allowing crystallization, and hand-separating the left-handed and right-handed crystals. Biochemical reactions also prefer one enantiomer over another: most amino acids are enantiopure, and the L-form is used preferentially in biological systems.
Racemization is the process of an enantioenriched substance becoming a mixture of enantiomeric forms; the rate of racemization (from L-forms to a mixture of L-forms and D-forms) has been used as a way of dating biological specimens."
Yrekagrow, this is what he ment by "turning light"..... "the levorotatory form (the (-)-form) will rotate the plane of polarization of a beam of light to the left, while the dextrorotatory form (the (+)-form) will rotate the plane of polarization of a beam of light to the right."
merf, the word you are using means GRAPES and NOT truning of light! <shaking head>
