This is a very neat way to add math to a web page. It's as easy to use as typing in TeX and much portable than the right way of doing such things.

Sand pit on a beach

As an analogy to the consciousness in a physical system, the water shows when the pit is dug deep enough. Similarly, consciousness shows when the system meets certain criteria. Just like the water is from the same body for all the pits. Consciousness is the same phenomena for all individual systems. Since we can make a channel between two pits or dig a big pit to encompass them, can we make links to connect conscious systems or merge them the form a bigger one?
