Huge, massive, gigantic wall murals plastered over academy walls rock...period. Take a look at my BJJ compadres over at F4 Martial Arts Academy in North Little Rock, Arkansas. It was painted by kids, yes KIDS I tell ya (with the aid of a projector and about 12 hours of hard labour).
Seeing that just gave me the most amazing tingling feeling inside, I mean it's just so cool to see something you created, transposed into another format by anothers' hand.
Tell you a secret too...when I was a kid, I got nicked for graffiti (or as I called it at the time, art) on walls. Oh how things have changed hahaha.
The F4 wall mural also reminded me of the huge blown up photos the adorn the walls of the Alliance head academy. Here's one photo courtesy of Michael Langhi's Facebook page:
It must be so inspiring to train under the watchful gaze (albeit in still form) of Michael Langhi, Luanna Alzuguir, Sergio Moraes, Tarsis Humphreys, Lucas Lepri, Gabi Garcia and many others.
If your gym has a wall mural I'd be really keen to have a look so pop a link in the comments section. Ta!
