I know it is uncommon to call out a particularly brilliant blog-post, partly because we read a lot of them already, but this one really struck me, about how to develop a magic-user's image and style within the constraints of a generic spell list.
The example he uses is a lightning/storm/crow-based magic, where Shield causes ethereal crows to flap around the caster; or Light, which crackle out of clouds with faded electricity. An example recently from Glantri is when blizack decided Goldfinch shot magic missiles in the form of eldritch, streaking birds.
We've started developing cool ways clerics turn undead - why not prompt creativity with the basic mage spell list, too?
