That is EXACTLY the opposite of what I was going to say. I love icons with transparent backgrounds, and hate the curve in the middle.
My Fav's are... Saucelifter Sway iBomber and the Taxi Ball one too, but it's changed for the sale right now.
Toki Tori DDR-S Seven Swords Zenonia Abigale (before update~ after update it looks extremely horrible) 三国演义 World of Tunes

DeBlob Fast & Furious PinkSlip iCutter Toki Tori Asphalt4 Sway 2XL SX Payback AC All NGMOCO icons I lyk quite a few icons... don't I ?
I like the icons of Sentinel 2, Siberian Strike, Star Defense, Orions and Snake Galaxy. I also think that ngmoco make absolutely great app icons. They are one of the few iPhone exclusive developers, and man do they make a good overall product. My favourite app icon though is Doom Resurrection. I think it's really smart to have the icon label as "Resurrection" below the Doom in the icon. I find good icon labels just as important as good icons, and I just got so annoyed with 7citiestd as an icon label that I deleted the game (I also had way too many TDs and 7 cities wasn't one of the better ones.) I also don't like icon labels like FlightControl. I prefer icon labels to be one word that's no more than 12 letters otherwise it make my springboard look cluttered and messy. Of course, I've gotten used to it overtime though. I used to use the "Rename" app from Cydia, but it messed up many things in 2.2.1 so I'm not using it for 3.0.
x2football looks very nice with my appiconoverlay, didn't even have to make an icon for it along with azkend and 3d tunnel vision
Some of my favourite app icons are Guns N' Zombies, GloBall, Light Wars, Star Ride, Edge, Grunts, Moonlights and Music iQ:
my favorites are: Isotope CS.Ones old icon geodefense light wars edge globall caster annihilation arena ExZeus sorry bout not having pictures of them
Nothing really comes to mind for me...maybe the Topple icons. I like the old Dropship and Sway icons too. Oh and 7 cities
Rolando 2, Car Jack Streets, wurdle, Topple 1 & 2, Star Defense, iGangster, Star Hogs, and nearly all EA games...
Real Racing Field Runners iTunnel 3D (The last one only really works on a black background, that's why it looks so awesome on the actual iPhone screen) The original Rolando and the Dizzy Bees have great icons too.
