 *grid1_0 has not been updated yet as the required lib "gifAnimation" is not updated for v3 yet.
 
-Mostly just moving stuff from setup() that is now required to be in settings() (good naming scheme there, not confusing at all...)
-
-According to the docs, "*The `settings()` method runs before the sketch has been set up, so other Processing functions cannot be used at that point. For instance, do not use `loadImage()` inside `settings()`.*" - [source](https://processing.org/reference/settings_.html) and "*If you must change the size of your sketch, use `surface.setSize(w, h)` which is the one and only (safe) way to alter your sketch's size.*" - [source](https://github.com/processing/processing/wiki/Changes-in-3.0) ... But! Using `loadImage()` in `settings()` works (for now ?) while ~~starting with a default sized window and then using `surface.setSize()` breaks a bunch of the effects - including my fav, ruttetraEmulator (see ruttetraEmulator\broken-ruttetra.pde for a non-working example that follows the docs (as of 2015-02-17) as I understand them.~~ Ok, so I had misread it, setSize happens on the NEXT `draw()`, so we just skip the 1st frame and this works as the docs say after all, see _ruttetraEmulator.pde_, and I'll update the rest at some point as following the docs will futureproof the effects.
+Mostly just making sure they follow the rule `Do not use variables in size()` - [source](https://github.com/processing/processing/wiki/Changes-in-3.0)
