Gene projector

“Looks like they've finished the gene projection. Let's see what you'll look like when you're all grown up.”— James

The gene projector is a device which is capable of predicting a newborn baby's future appearance as a young adult by extrapolating physical characteristics from his or her genome. In Fallout 3, this device was used by James to show the Lone Wanderer how they would look when they "are all grown up".

Accessing gene projector

Facial reconstruction

Other than at "birth", there is only one other opportunity to use the gene projector to change the character's face: just before exiting Vault 101 after the escape! After that, the only facility to alter one's facial appearance is with the lasergrafter in the possession of Pinkerton in the Rivet City bow.

Haircut

Even though only Pinkerton allows changing the character's face after the tutorial, there are multiple characters which allow changing hair-style:

Owning a house in Megaton, the personal robot butler Wadsworth can give a new trim or shave one's beard. Godfrey in the Tenpenny Tower suite offers the same service.
A haircut can be recieved from Butch when encountered during Trouble on the Homefront or if having him as a companion.
A haircut is also available from Snowflake in Underworld.
It is also available from Joseph in Little Lamplight.

Notes

A gene projector can be seen in the medical area of Jefferson Memorial, located in the sub-basement.
Another gene projector can be seen in the upstairs area of the REPCONN test site in Fallout: New Vegas, upside-down. The far right button on this unit is labeled "Body" instead of "Hair".
Yet another can be found in the medical area of the Brotherhood of Steel's Hidden Valley bunker, turned sideways, in Fallout: New Vegas.
It is unknown which pre-War company developed and manufactured the gene projector, as there is no company logo on the device itself.
