This heart-shaped puzzle is a toy that is both educational and entertaining. Called the Gentoy and designed by Russian artist Veronika Fillippova, this puzzle is an anatomically correct model of the human heart.
Each part of the heart-shaped puzzle is marked by a unique letter from the DNA combination GATC. Fillippova did this hoping to evoke interest in genetic engineering. The puzzle is a wonderful way to figure out how to put the pieces of a broken heart back together.
