Hi mbsaulto,
Thanks for the additional ideas!
I think I like the single < symbol the best like
#386.
#384 - Very creative! I like the grate. Can you try a horizontal version instead of square? Can you also try removing the dots in the corner? (simulated bolts?) Keep the text still right justified...
One last idea if you have time - Can you try something where all the letters MSG are half off the design like #331
Thank you so much!
