+### [openEtG]
+
+![openEtG login screen](openEtG.jpg)
+
+[openEtG] is an open source engine that is an HTML5 successor to the original
+[Elements the Game][Elements], featuring additional cards and balance.
+In December, 10k lines of JavaScript source were rewritten in Rust:
+
+> Overall I've been brainstorming this change for a couple years. So I'd already
+> shifted from a classical OOP mess with Shield/Weapon/Pillar inheriting from
+> Permanent to one where everything is a Thing. This also made sense because in
+> openEtG there's spells like Flying Weapon which convert the player's weapon
+> into a creature. So before I'd create a new Creature filled in with stats from
+> original weapon, whereas now it's mostly just moving the instance into a
+> creature slot & updating its type tag.
