Pattern is a string between two and sixteen characters in length. The length of pattern determines the number of colors used by the ant. Each character represents a rule for a specific color. For example, the pattern LRRL means:

• Turn left on a tile of color one (black)
• Turn right on a tile of color two (white)
• Turn right on a tile of color three (blue)
• Turn left on a tile of color four (green)

Tiles change color in a cyclical fashion (black -> white -> blue -> green -> black).

Valid pattern characters are:

• L or l (left turn)
• R or r (right turn)
• U or u (u-turn)
• N or n (none)

• q - Quit
• p - Pause/Resume
• r - Restart
• 1 - Slow ant speed
• 2 - Medium ant speed
• 3 - Fast ant speed
