I really don't know what it means but I found English letters 3, M, W, E fascinating just replica of each other reflected or rotated horizontally or vertically.
You may think it looks like Text Alignment icons in any Computer Graphic tools e.g. Adobe Photoshop, Adobe Illustrator, Pixelmator etc. but believe me it's not.
I hope you like it.
Thanks & Regards
