A cute little icon I had Mistsage from FA make up for me. I couldn't help it after stumbling upon their page and seeing the awesome potential there. xD
And if you're more into Pokemon than the average joe, yes that's a modified Team Rocket Pokeball. Usually the bottom is red but I thought white would be more fitting.
If you're interested in getting one of your own, check out their page and see if there are any slots open! They're only 2$ as of this post. :D
