A "bad guy" was looking for someone to take over the mapping of the 10th dimension project (using a big computer) and found a British man who aparently had no credentials... a janitor of sorts. However, you and I know him as Dr. Who, the hero of our story. He, unfortunately, does not realize his own importance and goes to work for this fellow.
In working, the Dr. produces several artistic chaotic renderings and a diagram of a city. The bad guy asks how he did these so quickly (quicker, his cronies say, than any other computer tech so far), to which the Dr. explains it just came naturally. He did it entirely without the computer, which is still broken.
The bad guy looks at the papers as imaginary rubbish. [I assume the bad guy will throw him out, only to discover the true worth of the drawings later, but we'll never know, will we? 'Cause I woke up!]
