Moon videos at Arunn’s Unruled Notebook! Have fun!
PS: It was a bit moving to see the videos and get reminded of those extraordinary lines of poetry from Bharathi (which, in my mind, I always hear as sung by MS):
சந்திர மண்டலத்தியல் கண்டு தெளிவோம்
(We will understand the nature of the lunar regions!)
