These are Spaceship rotation sprites. Each one also includes a 100x100 icon. Some of them have been compressed down to a small number of colors, but I've included them all* in case someone wants color-limited sprites. Most are rendered at an angle, but a few are top-down. There are about 74 ships to choose from. They where originally made for Escape Velocity mods, but I've obtained permission to release them here.

The files have been extracted into pngs, and I took the liberty of creating alpha-PNGs out of the sprites and masks so that you don't have to, but the Hook ships could probably be re-masked better than I managed to (by touching up the mask.)

*The X-Wing was not included to avoid copyright infringment, but the Star Trek style ships appear to be original, though highly derivative, designs.
