Objectdock Icon

The .ico icons that are included in some downloads are just bonus extras...should someone want to change their desktop or start menu icons. I haven't seen a roller coaster .png file here, but you could probably easily make one...just find an image of one and fix it up in a graphics program (Photoshop, PSP, etc.) then save it as a .png graphic at around 192x192 pixels in size.

I think ico files use less memory in objectdock...they should work the same as png's. But the highest resolution you normally find them is at 128x128, which is great if you don't mind their zoom size that small.
