Don't know how many of you are familiar with GURPS, but I found and advantage I would like to port and would like you input

The Advantage is "Visualization" basically you concentrate for a minute. The player describes the scene as they envision it, what they would like to do, and how. They make an IQ roll, and the degree of success turns into bonus dice on the action they wish to preform -Modified by how closely the actually scene resembles the described scene. In GURPS this advantage, is not only used by people, but to handle the modeling and simulation powers of an AI.

It think is would make a very nice adept power / meta-magic. Something along the lines rolling (magic + logic) - 1*(number of incorrect details) before the actual roll, with hits adding bonus dice.

Sounds like a form of Centering to me.

Centering offsets drain, this would give bonus dice. I could see it as an advance form of centering

Since the GURPS community considers Visualization a cinematic advantage, I'd make it an adept ability.

...since it is also mentioned in the context of AI's, I would make it a Positive Quality so that it is available to both awakened and mundanes.+

In RL, I have used a visualisation technique for learning musical scores. This was promoted by the intuitive concert pianist/piano pedagogue Walter Gieseking (with Karl Leimer) in his book Piano Technique (Dover Press 1972).

Part of the technique involved reading through the score and "visualising" the piece without sitting down at the piano. Once the work was committed to the mind, then I would go to the piano and play through it without having the score in front of me. This allowed a for greater degree of concentration on the more subtle aspects of phrasing, timing, and expression without the distraction of the printed notation. The strange thing, it really worked.

It got to where I could look at a score and "hear" the music in my mind note for note, even complex harmonic structures such as those used by Debussy, Messiaen, and Stravinsky. I would commit recital programmes to memory this way because I found having a page turner sitting next to me and reaching across my field of vision every so often to be a terrible distraction.

Sometimes this can be a distraction, as I can often "replay" compositions that I know, be they for piano, organ chamber group or symphony orchestra, and hear them as if I were listening on a portable playback unit.

Ah right, thanks. Good way of remembering.
