The Encore by Rhythm Clocks features a very unique motion. While the clock plays one of the 18 melodies the clock's numbers rotate in pairs as shown in the pictures. The pairs of numbers spin 180 degrees and then rotate back to their starting position. When the numbers rotate, they reveal figures of swans and dancers.

The avian retina rhythmically expresses several clock genes in vivo. Bmal1 and Npas2 are highly rhythmic in LD and DD, with highest levels during the late day and early night [27]. Clock mRNA is ... expressed in chick retina, but with a low amplitude rhythm [32]. Cry1 and Per2 transcripts peak during the beginning of the subjective day [33,34]. Cry2 mRNA is also expressed in chick retina, but its temporal expression pattern is unknown [35]. The clock in the chicken retina also controls the expression of Aanat in photoreceptors [16,17].

Rhythm Clock's Voyager is another version of the Timecracker, the Top Selling Rhythm Small World Clock for years. The Voyager's dial features an antique map of the Americas and the Pacific Ocean. On the hour, the face splits in two and rotates 360 degrees while revealing three colorful spinning dials with dolphins and one with a compass. The Timecracker Voyager from Rhythm Clocks features a real wooden case shaped like a ship's wheel. It plays 12 popular songs or 3 Christmas song ...click for details

Using genetic approach, a single mutation (A to T) in the Clock gene affects circadian rhythmicity in mice. Clock has been mapped to chromosome 5. Mouse Clock encodes a transcription factor, single polypeptide chain of 855 aa (predicted calculated mol wt ~97 kDa; pI 6.52). The human homolog is 846 aa. It has significant homology with the mouse NPAS2,

Results: Cultured neural retina cells exposed to a light-dark cycle showed rhythmic expression of clock genes. Bmal1 and Npas2 (... known as Mop4) peaked late in the day in LD and in DD. Clock mRNA was high at night in LD, but arrhythmic in DD. Cry1 and Per2 transcripts increased rapidly in the early morning and were low at night. The rhythm of Per2 was reduced in amplitude in constant darkness (DD). Levels of Cry1 and Per2 transcripts were stimulated by light exposure at night.
