+## Challenge: Halloween Prints

+Entries covered four main areas:

+- **Spooky decor.** Skulls, spiderwebs, ghosts, LED tea light pumpkins, and wall hangings.
+- **Articulated and mechanical prints.** Print-in-place bats, articulated skeletons, and moving decorations.
+- **Specialty materials.** Glow-in-the-dark filament, translucent or color-changing materials, and multi-color HueForge art.
+
+### Submission requirements
