The blonde took the day off

The next day at work, it turned out that the tall blonde took the day off. This was just the opportunity to access her PC that he needed. Fred waited until lunchtime when nobody was around her office and went in and placed a bootable DVD in her computer's DVD drive so that it would install the sequence of basic light pattern programs, and then his additional private program, the instant she booted her computer the next morning.

Fred snuck out and could barely wait until the next day to see what the result of his first experiment would be.
