Arachneuron's World

The Arachneuron is a hypothetical computer model of the human cerebral cortex (the thinking part of the brain). It lives in a digitally-generated world, and will eventually have access to its own internal web browser, giving it access to the World Wide Web. Its visual field is 512 x 512 pixels, and each pixel is 24 bits. When exploring its world, the Arachneuron can pan up, down, left, or right one pixel at a time. It can also read a Boolean value which is false if its attempt to pan one pixel was denied. It can move its internal mouse cursor up, down, left, or right one pixel at a time. It can start holding its mouse button down or stop holding it down. It can sense if the teacher's mouse cursor moves up, down, left, or right one pixel. It can sense if the teacher's mouse button is down or up, and whether or not the teacher's mouse cursor is active or hidden.

It can read a string of ASCII characters. The first byte is always a number between 128 and 255, and is an index into a voice table. Each person or entity currently interacting with the Arachneuron has a unique voice table no. The teacher's no. is always 128. The Arachneuron can request an entity name, causing it to read the user name (a string of ASCII characters) of the previously active entity. Any ASCII character greater than 127 is treated as a signed integer between -64 and 63 (one possible use of characters greater than 127 is to represent musical notes). The Arachneuron can write a string of ASCII characters. If the previous string written by the Arachneuron consists of up to 3 characters all between ASCII values 1 and 3, it is treated as if the Shift, Ctrl, and/or Alt keys are being held down. If the previous string written by the Arachneuron consists of a single ASCII null character, it is treated as if no modifier keys (Shift, Ctrl or Alt) are being held down anymore.
