DIY sky : romantic star projector
The Romantic Star Projector is special. It's available from Infmetry (which means "information symmetry, the condition in which all relevant information is known to all parties involved") and they describe the projector best:
This star projector projects a map of the heavens onto your ceiling and walls with thousands of stars in random order.
Featuring a rotating base with compass-point alignments, it is possible to set up your AstroStar by aligning it according to your location and the time of the year, so it can project a map of the clear night sky all around you. You can also change it to the accurately track movement of the heavens as the year progresses.
The AstroStar projector not only gives your child an education of astronomical science, but also gives you the couple to create a romantic surprise! Ideal for astronomy or astrology fans, romantics, kids who appreciate a nightlight with a difference or anyone who wants to bring some starlight into their home.
$22 in blue, white or yellow LED from Infmetry.
