here's some fun art work that ive made in the node editor of houdini. Yes, in the node editor. No photoshop. Im calling it NodeZArt.. cuz its simply art with nodes.. and it has my initials too (ZA)..
how are you able to get the color of the image per pixel? I am assuming a script reads the image pixel by pixel and for each pixel drops a node and set that color.

yup u r partially correct… im reading the image into houdini and converting it to point data so that i can adjust the resolution within houdini. then im using a python script to read that info and created the nodes accordingly.
took an image sequence, converted it to point data.. since the point numbers were changing on each frame i made an ID like attribute that remains consistent.. then wrote a Python script to convert the points to nodes.. where the node names were same as the IDs.. this was a very slow process..
What i figured out was that changing the color of an existing node is faster than creating a new node. So i checked if the current node (point) was present in previous frame, if yes then change color of existing node else put a new node. And in the end of the loop i checked if any node were present in previous but not in current then delete the nodes. This sped up the process quite a lot.
OMG this is so good. This style of the images generated with the nodes never gets old. It's also quite intriguing how a few small colored rectangles tricks our senses in such a flagrant way. It's as if I've never heard of pixel based displays. Our monkey brains are both staggeringly primitive and capable of greatness in the same time. I've read it in a “pop-science” magazine.
