5 out of 5 starsI am so happy with my math formula art! Michael is very helpfull and creative and shape is carved in real wood! Highy recommended. I ordered math formula in special shape: 12*cos(10* sqrt((x/100)^2 + ((y/100) - sqrt(abs(x/400)))^2)) / (1 + 0.5 * ((x/100)^2 + (y/100)^2))

Thank you so much for your order! This was definitely a surprise when I generated the surface, and it was an interesting project to see come to life. I hope you enjoy it, and hopefully, until next time!

I've always loved building things. My background is in electrical engineering, and robotics, but I've also had a lifelong passion for woodworking and creating with my hands. Connecting those two passions gave birth to TerraMadera.
