Curiosities!

Curiosities! adds assorted blocks and items that are not part of vanilla Minecraft. Several are built around redstone and rails: a block that makes a powered redstone component vanish for five seconds, a rail that lets minecarts pass in both directions, and an elevator-style block that moves a player up or down when they jump or sneak, though it only links to other elevators of the same color. Other items cover falls, light and music, including boots that bounce a wearer like a slime block without fall damage, a helmet that gives its wearer light level 10, an angel block that sends broken blocks straight into the inventory, and a minecart that plays music.

The mod is published for Fabric only, for seven release versions covering 1.21.10 – 26.3. Only the server needs to run it, and players can join without installing it, because it is built on Polymer, which lets server-side content work with vanilla clients. Polymer is a required dependency and must be installed alongside Curiosities!. The source code is public under the GNU Lesser General Public License v3.0 only, and snapshot builds are published.
