Use the sliders to choose what a body part looks like. Click "Randomize" to get a random face.
I took inspiration from Brain Challenge, which is a brain-training game I have on my Xbox. There is one minigame in which they use cards with pictures of people on them (Which, in my opinion, look a lot like Nintendo Miis). One card is displayed at the top of the screen, and three cards are displayed at the bottom of the screen. You have to choose the card from the bottom that looks like the one at the top.
