its not an easy thing to narrow down inspiration if everything you see can inspire you.
If I was to change the topic towards what sort of design/designers do I like ...
jean paul gautier
charles renee mackintosh (I got into him well before the revival of his stuff)
hr giger
frank lloyd wright
phillippe starck as I've mentioned elsewhere
japanese designers (link to a blog) and of course their anime (its on a completely different level storywise to western stuff) - Torii Yoshinori and the gonzo and bones studios especially.
Stephan Martiniere
But I also pay a great deal of attention to cg movies (vexille, appleseed, appleseed ex machina and final fantasy: advent children for example), they're great for giving me tips and tricks in relation to my work as was
pocoyo (kiddy program voiced by stephen fry) suprisingly even though it isn't my exact field of cad.
New designers doing 2D work don't really inspire me as its usually pretty similar to work that has been done for many years, its very rare that you get a completely new approach to typography for example.
But it doesn't mean I necessarily apply their work styles in my own, I've got my own style of presentation etc
