Tuvas posted this great top-ten list over on Unmanned Spaceflight.

I changed it around a bit, hope you don’t mind, T!

1. You consider any image with less than a billion pixels a mere pittance… a negligible amount of data.
2. You realize that any part of Mars can be interesting, if viewed at sufficiently high resolution.
3. You start to see in black and white away from the “Center strip” of your eyes.
4. You have decided to buy a 500 Gigabyte drive just to store a few dozen of your favorite HiRISE Images.
5. You’re considering getting a new 40″ LCD mainly to look at HiRISE Images.
6. You know what JPEG 2000 is.
7. You start making up new Hi Names (HiStuff, HiSpace, etc, etc).
8. You continually refresh the web page starting Wednesday morning, waiting for the next release.
9. When using Google Earth, you wish you could zoom in further, just like HiRISE can.
10. You’re reading this!
