Japan-based illustrator and designer Akihiro Mizuuchi, apparently unsatisfied with regular old plastic LEGO, has gone and designed a mold for casting LEGO bricks out of chocolate.
The bricks appear to be at least marginally functional. Enough to snap together into the designs seen here, anyway, until they melt. More importantly, of course, they're edible.
See more of these LEGO confections on Akihiro Mizuuchi's Behance page.
