Engraved

At morning i was on my usual route to work in Kamppi, Helsinki. Suddenly i noticed something on tram rail. On that heavy, hard, iron rail was engraved some logo. My boys are huge transformers fans and i recognize that logo is from transformers. It's logo of decepticons, bad guys from transformers. It was engraved deep to that rail so no "Average Joe" could do something like that. What it means? Megatron are here? We need Optimus Prime to save us? Don'n know, but there it is and first thing when i get home i show this image to boys.

Nice Weekend for everyone!
