Animated pillars wallpapers are great, and you just reminded me of the wallpaper galleries the Cave games console and PC ports feature: you can set a timer to change the wallpaper every xx minutes, like on a computer OS.
It is actually useful considering the sensitivity of some displays prone to burn-in, like plasmas of yore and today's OLED that hate static objects (in-game HUD, logos, whatever)
EDIT: ugh, implied question; can BGFX do that too ? if not that might be a thing to consider for the future, OLEDs are slowly but surely getting more affordable and popular.
