New: Dashboard Widget Version (requires OS X 10.4 Tiger)
This is just a Sidereal Clock for Mac OS. It displays local sidereal time, Universal Time, and the Julian Date for the currently selected location.
Right now the set of locations is hard-coded in, but it's fairly easy to change in the source code (which is available under the GPL). I'll hopefully get around to making this more easily user-configurable at some point, but this is my first attempt at Mac OS programming with Cocoa and Xcode so I started with the basics for now. :-) The locations currently include Lick, Keck, AEOS, Palomar, CTIO, and the VLT. If you like this software but need additional locations defined, let me know and I'll happily add them to the list.
SiderealClock.dmg contains both the executable and the source code. Better yet, grab the new Dashboard Widget Version. I just hacked this together last night, so it may be a little buggy. Let me know if so! You can now add new sites much more easily by editing the SiderealClock.js file inside with widget bundle.
