Good Moon Rising

Put this on the bedroom wall, and they'll think you hung the moon. Really. The Moon In My Room" is a detailed convex moon, 10" dia x 3" thick at the center, from Uncle Milton®. It will turn itself on in a darkened room (it's night-light bright, like the real moon) and run automatically through all (12) phases in 5-second intervals, or in manual mode with you at the remote control. The lamp takes (4) "AA" batteries, the remote takes (2), and you're buying. Includes a 15-minute audio CD tour of the moon, and has (3) slotted mounting holes on, you should pardon the expression, the dark side of the moon.

Poor Man's Luminaria

It's a little 2-1/2" square base with brushed-aluminum-look sides and a mirrored top, in the middle of which 3 colored LEDs flash on and off in individual and combination patterns.

Line up a dozen or so on the front walk and you've got the world's first flashing multicolored luminaria show for party nights. You add (3) "AAA" batteries.

Beauteous Brass Sextant

Sextants came along after astrolabes but before GPS. (Just like you.) They're used for finding latitude and the distance between objects, and are still the non-electric, non-satellite-dependent back-up for navigators. Ours is a beauty in solid brass with glass optical components, at a tiny price. Measures approx 4-5/8" x 4-1/4" x 3-1/4" OA and comes in a very nice wooden case. Includes instructions for use, which you're going to need unless you went to Annapolis where they still teach it because computers can still go all kaflooey. (Note that well before computers started going kaflooey, compasses and sextants lost an adventurer here and there, too, so don't call us if you and the sextant set out for Madagascar and end up in Iceland.)

The dog is amber, 8" across x 5-3/4" tall plus a 3/8" tab. The jumping dolphin is 7-1/2" long x approx 4" OA, and bluish-clear. Behind its tailfin is a separate 4" dia red ball with a 3/8" mounting tab. The fish skeleton is neon green, approx 5" wide x 9-3/4" long, plus a 1/2" mounting tab. The heart is fittingly red, approx 6-1/2" across x 9" tall, plus a 1/2" mounting tab. A smaller heart is cut from the center. All are 3/32" thick with a paper backing.
