Idea totally taken from Paladin thread, but since Shamans have actually no cosmetic/fun glyphs, here is a thread where they can be suggested. It was slightly disappointing changing main from a warrior to a shaman, warriors have lots but shamans have none. I actually, on both my specs use one Minor Glyph, and that is the Spectral Wolf, because i'm not sure if they fixed the Glyph of Waterwalking bug yet.
Go!
EDIT: The glyph that makes one totem give 3 other cosmetic ones out, is pretty ugly so I didn't count it. Don't mention it
EDIT2: Ok, turns out with thinking I can have some ideas:
Glyph of Healing River: Adds an animation of a direct beam to allies healed by Healing Stream Totem.
Glyph of Elemental Grace: Adds a green/grassy effect under the player when affected by Spiritwalkers grace.
Glyph of Healing Delta: Adds an animation of a direct beam to allies healed by Healing Tide Totem.
Glyph of Magma Totem: Adds a lava pool effect to the radius of Magma Totem.
