Bocchi the Block!

The block is controlled with right-clicks, which switch it between panicked and unpanicked states. While panicking, a player inside a 64-block radius walks forward, and a Magma Block in front of the Bocchi Block makes that player turn around. Magenta Glazed Terracotta arrows, within an 8-block radius, can turn a panicking player as well. A direction arrow on the block shows which way it faces.

Redstone signals can start and stop the panic state, and a Note Block placed above the block plays a guitar sound when it is triggered. The block also emits a comparator signal that depends on whether one or two blocks are panicking, and several Bocchi Blocks placed in a line send the players in the line backwards, first one facing backwards. The author notes more blocks are planned.
