My daughter has sculpted our likenesses as LEGO Brickheadz.
The LEGO Brickheadz Brick Me kit is fairly awesome. My 11 year-old spent an hour or so on each of these, and was excited to point out she put a cool surfer logo on my hat.
Amazon currently has these 708 piece sets for $24, which is below list price.
