[DRAFT] Tower, defense/landing pad, with functional clock

Universe first? Tower with functional clock!

The building is mainly intended as a defense tower for the upcoming territorial warfare with its 24 pads, but will fit equally well for an office or as a landing pad for smaller ships or any other application you see fit.

The programming boards are loaded with my original open source du-clock (https://github.com/PerMalmberg/du-clock) so they can easily be replaced/relinked with DRM-free boards and reloaded by the buyer, or I can alternatively release the DRM for a small free that covers the travel cost and time to avoid re-linking all the elements.
