Most of us think of our roller blades as fond memories of the past, or a way to get to work faster, but I can certainly say I have never thought of my skates as a possible brush to use to create a work of art, especially not a Chinese style landscape ink painting!
Keep watching until you see the full landscape--I'm being honest when I say I wasn't initially impressed with the style (she's basically using the blades as brushes, not skating at high speeds like I expected), but the fact that she was able to envision and create such a huge work on ROLLER BLADES is insane!
Also, her legs must be so in shape, because there's just now way I could do those kind of stroke motions while on skates. Nope. Nope. No.
On the other hand, this might be really fun to try to recreate.
