So is it possible to give Anivia's frost effect a more unique look than just a Rylai's slow?

One thing I've noticed is that if I try to catch enemies at the edge of my R, it's not immediately apparent whether they've been hit or not until they take a few steps and notice there are some white frost on the ground they walk. This is made even less apparent when they happen to be bunched up around other units who may or may not have been hit by her R.

Combined with the fact that her slow effect actually has gameplay relevance to her beyond more than just a simple slow, is it possible to make her slow have a more distinctive appearance than just what you gave to Rylai's?

It's very similar to 's poison where trying to fish out which enemy is affected or not screws you over the moment your enemies decide to have an orgy and lump together. Only difference of course is one of them is thematically ****ed over while the other is a bird.
