Compiling a list of the Galactic Graffities has been something I've wanted to do for a long time, as they have been quickly fading among the many systems now on record thanks to the modern luxury of the Journals.
So please, if you have added any interesting, nice, smart or dumb tags to the galaxy map: Please speak up and share some background! We can help you, and you can help us putting together an awesome collection, documenting this dying profession. I'll make a start:
"Hi, my name is CMDR Redfox, and I confess to the following..."
Trilateration-Help
Coriolis
DWE-Logo
Thargoids
Misc. & Acknowledgements
Cobra - planned, but not completed: One of the projects that didn't make it. Partially due to time constraints, but also due to graffiti becoming ever more common. Maybe in the next galaxy.
Last but not least: Acknowledgements and much needed thanks to:

Trilateration-Help
[Feb 2016]
Preparation: Identify the coodinates and find fitting systems on the ED Galaxy Map. Reason to do this: Resolve coordinates of systems far out (arc) and as far above/below the galactic plane as possible (vertical rows), thus helping fellow explorers trilaterate their positions more easily with these outlying reference points.
Completed: After remotely trilatering the systems and resolving their coordinates the systems can now be displayed on the EDD 3D Map (green highlighting added).

Preparation (1): Finding a suitable and 'free' spot by overlaying EDD 3D Map and Galaxy Map. Also important for sizing, making the full Coriolis structure nearly 6 kly wide.
Preparation (2): Mapping coordinate-points to a Coriolis outline and identifying fitting systems in the ED Galaxy Map.
Progress: Again, remotely trilaterating the systems' positions, which at least take 4 distances from different positions to resolve - but usually more, because ED doesn't give the required distances in full precision (only 2 decimals).
Completed (1): Close-up as seen on the EDD 3D Map.
Completed (2): Full galaxy view. As a side note: The DWE-trail can be seen quite clearly, having concluded a few days before.

[May 2016]
Preparation (1): DWE having been such a great and unique experience within ED I chose to pay to the expedition by recreating the unmistakable expedition logo. Finding a suitable and 'free' spot on the EDD 3D Map (no lack of systems as this is close to the core). Also important for sizing.
Preparation (2): Mapping coordinate-points to the lovely DWE logo and identifying fitting systems in the ED Galaxy Map. The 440 involved systems reuiqred much more trilateration work than expected (you do the math). I was glad to accept help from the usual helpful CMDRs - see acknowledgements at the end.
Progress : Again, remotely trilaterating the systems' positions. Did I mention that was a lot of work?
Completed (1): As seen on the EDD 3D Map. Fun anecdote: You see the line of stars touching the logo at the top-left? A random CMDR decided to start trilaterating just then and there and would have flown right through the half.finished logo. With the help from EDD and EDSM that CMDR was easily identified, contacted and after (somewhat awkwardly) explaining what I was doing he was nice enough to postpone his trilaterations. Gotta love your fellow explorers!
Completed (2): The logo as seen on Gerdofal's Map (with the colours showing how long ago a system was trilaterated).

[Feb 2017]
Preparation (1): Finding a suitable and 'free' spot by overlaying EDD 3D Map, which is becoming increasingly difficult since the introduction of the coordinates in the logs, which resulted in many 'lines' of systems becoming visible on the map.
Preparation (2): Again, mapping coordinate-points to an outline (compiled from 1984 Thargoids) and identifying fitting systems in the ED Galaxy Map.
Complete: For a change this wasn't remotely trilaterated, but rather flown with the trail creating the desired form.

Last but not least: Acknowledgements and much needed thanks to:
- Finwen and the great team at EDD for their awesome tool (and actually introducing many functionalities to make our trilaterations easier)
https://github.com/EDDiscovery/EDDiscovery/releases/latest - Anthor and the admins at EDSM for much explaining and helping out on many occasions
https://www.edsm.net - The great fellow explorers who helped with trilaterating; mainly CMDRs Zafford, Cruento Mucrone, Sparneejuah, herzbube
