From the cool things visible while Noble Ape is running, you might fantasize that kinds of sophisticated, amazing stuff is going on underneath. However, perusal of the source code (10K lines of bad C, including lots of hard-coded tables of constants), shows that the pretty "brain activity" graphics are just that: pretty graphics, with nothing particularly deep going on underneath. They look cute, but there is very little "brain simulation" going on here. For example, the code says "if in water, ape is awake; if at night, ape is asleep" -- very limited logic. Internally, Noble Ape just does the bare minimum required to produce its cute graphics. The cognitive and environmental modelling in The Sims games is 20 years ahead of this app.
