I decided to remake the icons on my taskbar as an exercise. They actually turned out a lot better than I expected. I made them all 32 x 32, but some of the circular ones are slightly smaller. The icons are for Google Chrome, Blender, Unity, Winamp, Battle-net, and Photoshop. I also had a Skype icon that I made, but I was unable to replace it on my taskbar because it doesn't work from shortcuts. The Battle-net Icon is messy, but it actually looks pretty good on the taskbar.
