The two towers.
Should it really be about these two (Barad-dûr in Mordor and Orthanc in Isengard), or maybe something else?
No hidden messages this time – at least if one is capable of reading Tengwar, the written language of Middle-earth.
“Practice Random Kindness and Senseless Acts of Beauty”, written in the Tengwar-Annatar font by Johan Winge, can be found at the bottom – hopefully without too many typos.
(The first one has been found already: An additional “d” has crept to the end of the line. Fixed now – thanks go to Uwe Engelmann for reporting it.)
On the right hand you can find the current year (written in Tengwar using the elvish duodecimal number system) and on the left hand the number “42”.
