"Why does a creative person create? It's a type of compulsion. I like to explore new ideas."
- Bart Kosko

The mouse brain is used as the computer; the programming is accomplished by imposing the mind of a human being:

"Do you need the mouse any more?" said the first technician.

"Yes," said Tiga-belas. "One-third of a millisecond at forty megadynes. I want him to get her whole life printed on his left cortical lobe. Particularly her screams. She screamed badly at ten months. Something she got in her mouth. She screamed at ten when she thought the air had stopped in her drop-shaft. It hadn't, or she wouldn't be here. They're in her record. I want the mouse to have those screams. And she had a pair of red shoes for her fourth birthday. Give me the full two minutes with her. I've printed the key on the complete series of Marcia and the Moon Men—that was the best box drama for teen-age girls that they ran last year. Veesey saw it. This time she'll see it again, but the mouse will be tied in...

"I'm putting the girl's whole lifetime into one-third of a millisecond at top power. It will drain over into the mouse-brain inside this cube. What is the normal human reaction within one-third millisecond?"

"Fifteen milliseconds—" The second technician started to speak and stopped himself.

"That's right," said Tiga-belas. "People don't get anything at all in less than fifteen milliseconds. This mouse isn't only veneered and laminated; he's fast. The lamination is faster than his own synapses ever were. Bring on the girl."

The first technician had already gone to get her.

The second technician turned back for one more question. "Is the mouse dead?"

"No. Yes. Of course not. What do you mean? Who knows?" said Tiga-belas all in one breath.
