This is my second design for my Cartesian series!
If you don't know, z²+x²+y² = R² is the equation of a sphere on spacial geometry (with the center on the origin, specifically).

If you like math, if youre a geek, if you study engeneering like me, or if you just like this design, help me oout!

comments and critiques are always welcome!

nice serie maaan!

o this one is a must have.

i like this ALOT! great job.

thank you very much cnachbauer!

Maths + Art = Win

Very cool. Elegant design and elegant maths.

this is rad! i don't much care for the text on back (especially in that boring font), but the front design is super print-worthy!

bio bot, the intention on the font was to make it look like as if it was handwritten, like on blackboards!

thank you all guys

the font seems out of place, and it doesn't look like it's handwritten because it is way to perfect and formal. but, i like the design and the idea.

I agree with Bio-bot. I'm not feeling the font, but that design is really slick. The best out of your series for sure.

yeah i kinda feel what you guys are saying

i hate math but his calculation is interesting!!!

Einstein mode: ON!! $5

please comment and vote my design thx :)

I would make the X, Y, Z on the planet more pronounced. My only real problem with it is that real geeks would know that the earth is far from being a perfect sphere. ;-)
