Quite like the Aurora Block in TF given their slow glowing effect depending on where they are placed but... would be nice to have support for Twilight Forest Blocks in general. If it's doable.

...I wonder if it's even possible to support the Yellow/Pink/Violet/Blue Castle Blocks & Reappearing blocks but perhaps not since those disappear & reappear when you right-click those. Not to mention some parts of the textures on them glows in the dark.
