I have depicted here the final scene of Andrea Chenier, an opera set during the French Revolution. The hero and heroine sing together one last time before stepping onto the cart that will take them to the guillotine. Let me tell you, a guillotine for Legos is probably the most fun thing I've made to date.
You can read more about this opera here.
You can listen to Sean Bianco's broadcast of the opera, starring Placido Domingo, here.
By popular request, here is a close-up of the Lego guillotine. Note the basket of heads.
