Week 18 – Challenge 2 – Comet

Challenge page : http://www.ancientsocieties.com/comet/

The Challenge text says The earth spins and life is short

The bottom left date 15-10-2013, the name of the challenge comet, and a Google images search help to find the picture shows ISON comet.

We have a 4 letters word ISON and 4 numbers at the bottom right of the picture 20-22-20-00

Life is short… A short word ?

Let’s make a basic cypher : Caesar rotate (SPIN like said in the challenge text) on the letters using the bottom right values to rotate each letter :

I ROT 20 gives C
S ROT 22 gives O
O ROT 20 gives I
N ROT 00 gives N (no change)

The answer is COIN
