This past weekend was Purim, a holiday in which Jews celebrate the defeat of a genocidal plot against them, as described in the book of Esther. Purim is a festive time, with parties and treats, but observant Jews also observe four mitzvot (commandments), as illustrated here in LEGO by Joanna Brichetto.
Mikra Megillah - listening to the public reading of the story of Esther (plus a related passage from the book of Exodus)
Seudah Purim - celebrating a festive meal (note Joanna's custom LEGO-scale hamantaschen, a traditional Purim pastry).
Mishloach Manot - sending gifts of food to others
Matanot l’Evyonim - giving charity to the poor
