Impossible colors are so cool.
‘“I would say you might get olo by staring at a saturated red spot and then looking at a green screen of a very saturated bluish-green,” he told me’
This is well established and easy to do, eg https://www.skytopia.com/project/illusion/ipage-et.html or https://en.wikipedia.org/wiki/Impossible_color#Chimerical_colors. I wish they had interviewed someone who had tried both.
There have been more impressive studies showing adaptation to completely new limbs like an extra thumb or a tail but this seems like it was more focused on pinning down the brain structures responsible.
I wonder if you could trigger a rubber wing illusion this way?
You could make a minecraft mod for this, probably? Find the brightest area in the webcam image, get the angle by assuming it’s a circle when viewed straight on, do some kind of calibration to map image xy to physical xy. The sensible way would be to use a wiimote but being sensible isn’t the point.
Skew binary trees. They’re an immutable data structure combining the performance characteristics of lists (O(1) non-amortized push/pop) and b-trees (log(N) lookup and updates)
They use a sequence of complete trees, cleverly arranged using skew binary numbers so that adding an element never causes cascading updates.
In practice they’re superseded by relaxed radix balanced trees.
You’re thinking of parallax, focal distance is about adjusting the curvature of a lens (or your eye) so that objects at that distance appear sharp
