Droste Effect and Infinite Recursion .tox

Hello world!

Sharing two .tox components recreating the famous Droste Effect and Infinite Regression with GLSL.

Code was ported to TouchDesigner and based on these articles by Roy Wiggins, available on his blog: Implementing the Droste effect in WebGL and Infinite Regression: Many Pictures From One Function 

On the Droste Effect:

• Scale affects the scaling in z, animate it for a cool effect!
• R affects the scaling of the input image.
• Ratio affects how "tight" the spiral loops, default is 1.
• Offset displaces the UV.
• Extend Mode sets the type of tiling.

On the Infinite Regression Effect:

• Scale affects the scaling in z, you can animate it too!
• Angle curves the regressions (0 is square copies, 1 makes a square spiral)
• Offset displaces the UV.
