+[Projectris][projectris] is like Tetris, but in 2D and 3D at the same time.
+As the 3D piece falls, you can manipulate it, but all that matters
+are the shadows it casts on the 2D game boards on either side,
+each of which is played independently.
+
+While the full concept is already prototyped, there are still many features to
+implement before this is a real game:
+scoreboard, increasing fall speed, game over, JUICE.
+
+[@bonsairobo] is not actively working on this, but is
+[happy to accept PRs][projectris].

+### [smooth-bevy-cameras]
+
+[smooth-bevy-cameras] by [@bonsairobo] is a small plugin for Bevy Engine that
+makes it simple to have [exponentially smoothed] camera transforms in your game.
+Just add a new bundle to your camera entity,
+and rather than updating a `Transform` directly, you can just update the `eye`
+and `target` values of a `LookTransform`, which will be automatically
+synchronized to the `Transform`.
+
+Several example controllers are provided as well:
+
+- First Person
+- Orbit
+- Unreal Engine Viewport
