2. What's the difference between the trial and licensed versions?

The trial version has several built-in limitations:
  • It's impossible to save changes to the settings.
  • The trial version will automatically blank your screen after a few minutes.
  • The trial version has tips which pop up intermittently.
  • The trial version will only work for a few weeks and will need to be re-installed.
If you register for the full version:
  • You can save changes to the settings.
  • You can create up to 20 custom configurations.
  • Additional artwork is unlocked.
  • You are entitled to all upgrades and bug fixes (which may include new artwork).

3. What happens when the trial version expires?

The screensaver will display a blank screen with a message indicating that the trial version has expired. At this point, you can re-install the trial version or purchase a license.

There are no limits to the number of times you can install the trial version.

4. Do I need to purchase separate licenses for different machines?

If you purchase a license, we believe that the license belongs to you (as a person) rather than to a machine. We don't mind if you install the screensaver on a reasonable number of machines.

The same license will work on any operating system. You don't need to buy a second license if you run multiple operating systems.

However, be aware that your e-mail address is encoded in the screensaver files.

5. Can I use the same license for my work machine and my home machine?

We don't have a problem with this. Even if you have a Mac at home and a Windows machine at work, the same license will work.

6. Can I give a copy of my license to a friend?

Well, we can't stop you from doing this. But, we don't recommend this for several reasons
  • Your e-mail is embedded in the license information.
  • If too many installs occur, we reserve the right to revoke your license. This means that you risk losing your license.
By giving your license away, you lose control of what happens to that license.

7. Do I have to pay an upgrade fee to download newer versions?

No. If you purchase a license, it will be valid for all updates and extensions made to the version 1.x series of the screensaver.

8. How do I find out about new releases and upgrades?

If you have an RSS reader, you can subscribe to the announcements forum using the smartfeed. News about any new releases or features will be posted to that forum.

9. Do you use any open-source software?

The Linux version made use of some open source software. These are listed in the "About Paper Pilots" menu entry in the screensaver. This links to the open source licenses.

10. What is an MD5 checksum?

MD5 (Message Digest Algorithm 5) is a cryptographic hash function. When we distribute a version of the screensaver, we compute the MD5 checksum for the download file. On your computer, you can also compute the MD5 sum (using the md5sum application) and verify that what you downloaded hasn't been tampered with.

11. What kind of 3D glasses can I use?

If you have red-cyan 3D glasses, you can configure Paper Pilots to draw in a stereoscopic 3D mode - just like going to a 3D movie. With red-cyan glasses, the planes will jump out and float above your monitor. There are several different types of 3D glasses. Currently, Paper Pilots only works with the red-cyan style.
