There is a photo contest by @friendlymoose called POBphotocontest.
Every week on Sunday a new round starts and the motto is announced.
To participate, you have to publish a post according to the theme, then leave a comment and a link in the contestpost and use the tag #pobphotocontest.
There are POB tokens to be won, which will be distributed as rewards for the published post.
Also @good-karma has donated Ecency points for the winners.
So it's worth joining in there.
This week's theme is blue and here is my contribution.
It's not that difficult to find something for every color in our company. If all else fails, it will simply be one of the many letters we have on display as decoration.
Here is an M in blue.
