A British Etsy shop owner, funky3Dfaces, will create a life-like LEGO head that looks like you (or your child) to replace the classic yellow head.
For $30.10 (includes international shipping), you can send the artist a few two-dimensional photos of you or your child to create the new head.
You can also request a custom hairstyle. The custom mini-figure head is shipped worldwide from Lincoln, United Kingdom.
The artist is currently offering a January special: buy two heads and get a third one for free.
