bit late...
I'd say a combination of things...to me they look like
- some are likely fractal's
- there's definitely some statistical data being plotted onto a graph in there (links project part 2), probably utilises some script on a website to plot a graph
- normal mathematical equations as plotted on a graph
- some look like images taken from a microscope and adjusted in colour/crop etc
- some look like they've been created using a wacom and photoshops tilt/rotate/fade brush tools
- some look like they've used a 'distortion grid' over an original image
- some look like splines have been rotated around the z axis to create the '3d spiral things' and then the whole 3d image is slightly rotated on the x axis to give it a slightly top down look
Also looks like she uses
Max Cycling 74 for some of the work...
COMPLEXITY GRAPHICS looks like it uses ies light data (basically it's the luminance and output shape of a light and is usually used in 3d rendering to give accurate lighting) for the shapes as in it's simplest form it's a graph plotting the light if it was seen 'laying flat on a surface' (see attachment)
