This is the first time I see zen garden art like this, it's awesome! What boggles me however is Pac-Man... how did you create his shape so fluently while the sand ends to his left? Or does the wooden frame come in after the sand art is done? Either way, applause to your skills, your gallery is gorgeous
No, the frame is fixed to the board. The shadow cast by the lamp helps somewhat to mask the entry point of those lines, but basically I started with the crux lines, by placing the rake, holding a finger on the pivot point, and carving the first four lines like so. Then, I just sculpted new lines around the existing centre point. As far as these things go, that was pretty easy. It was way harder doing the stones, actually. The sand is so delicate and fine, exit points are nearly impossible to avoid. So I decided to synchronize them.
In any case, thank you for finding me, and for these words. I'm so glad you enjoy my work. And, yeah, I'm pretty sure I'm still the only zen gardener who aims for referential design in their gardening.
