G.A.C. stands for Geek Astro Clock Geek for its geek-style binary display, Astro for Astrolgy, and Clock.well, it is for the Clock.
G.A.C is a binary clock, providing a unique way to look at your day: it shows the current time as a series of blinking stars. As starting point, its already not so bad, but the real interest of this application is its beauty: these stars shine on the magnificent night sky, surrounding one of the twelve astrology signs, crafted originally in the middle age by Johannes Hevelius.
You can select on particular sign or leave the program to show the sign corresponding to the current date.
Features of the G.A.C include 12/24 hours display, hiding/showing seconds, temporary decimal time display could be practical and educative as well and always-on mode: this turns off the iPhones auto-sleep allowing using G.A.C as a desk- or bedside clock.
Feel the weight of centuries, enjoy the timeless drawings of M. Hevelius on your iPhone and have as much fun with this binary clock application as we had during its development.
