You click through the options until you come across some interesting ones. A set of options allowing you to alter the entire human race. You can select either male or female and change anything and the machine will alter reality to accommodate it. You scroll through the options, changing size, shape, weight, even adding additional limbs.
You click on the man and start to play with numbers. First you make the model super muscular, then you reverse course and make the model obese. You fiddle with penis size, neck length, and life expectancy before restoring it to the saved default state.
You drag an extra arm over to the male body on screen and it attaches, a variety of others options also appear. Such as if only males have the extra arm, is the arm standard, and so on. You put the arm back and take it all in before smiling. Time to have some fun.
