Grand Theft Auto 4 Easter Egg - Tech Taggin'

Throughout the L.C. you'll see many graffitti spots with various things depicted - most probably inside jokes and such. Two of them I recognized as technical procedures used in creating active and interactive 3D worlds in programming - there may be even more in Rockstar's world. They must have really been hard-pressed for material haha.

The two examples are as follows:

NURB - Non-uniform Rational B-spline is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces. They allow for representation of geometrical shapes in a compact form involving the use of control points.
Consisting of Positional continuity, Tangential continuity and/or curvature continuity. Blam - how's that for excitement?!

KLIP - Klip is an XML file that contains markup, styles and JavaScript that provides the Klipfolio desktop dashboard platform with rules for the retrieval, interpretation, and presentation of arbitrary information sources such as web pages displaying text and image content. I can think of a million applications of this in-game. Certainly at Tw@ for sure.

I'll post the action packed photos of them when the egg is registered. Klip on!
