I found this really cool video at http://www.knowth.com
It shows 50 minutes of sunrise at Cairn “T” one of several megalithic cairns which are dotted around the Slieve na Caillaigh hills at Loughcrew in Ireland.
[EDIT! I forgot to mention, the 50 minutes of sunrise has been compressed into 40 seconds. ok, now have a peek.]
Is that too cool or what!
