'videogame ice effect'
I seriously love the over-the-top ice shaders used in all those early 2000s games. Ice always looked amazing, just this super bright white with pearlescent whitish-blue highlights that shimmered at odd angles and stuff. It's so cool.
Like the bridge tunnel in IceFields from HaloPC in 2003.
Or the almost-fully-transparent ice tunnel in Crysis Warhead (and firefall. Firefall had AMAZING ice shaders, it had some direction-based visual stuff going on where it had volumetric speckles all throuought the foot-thick ice).
Honestly: ice-themed anything looks cool to me, color-wise
He should try singing to them as well
