Become Computer

Become Computer is a real-time animated Brainf*ck (BF) interpreter.  BF is an esoteric, Turing complete programming language modeled after a Turing machine.

Instructions:

• Increment pointer (>) - press left arrow or D
• Decrement pointer (<) - press right arrow or A
• Increment value at pointer (+) - press up arrow or W
• Decrement value at pointer (-) - press down arrow or S
• Start loop ([) - press [
• End loop (]) - press ]
• Print to console (*) - press RETURN

Other Inputs:

• Undo last action - press DELETE
• Clear program and restart - press R
• Fast forward computation - hold F

A BF program starts with a contiguous array of integers, and a pointer to the first cell in this array. The program can move the pointer to the left, to the right, increment the value at the pointer, or decrement the value at the pointer. The program can loop with [ /*insert code*/ ].  A loop will only terminate if, at the end of the loop, the value at the pointer is 0.
