Hi.

Very Clever!!

Hi.

To be honest saw that kind of shape on a youtube video by Nick Saporito with sloppy as always details. This one is just a public domain svg with a polished structure and without two interrupting advertisements.

I've seen the impossible triangle. But I still can't wrap my head around how does this shape work. O_o I mean, I remember there's one or two games playing with this concept, but... It's so confusing. ._.
Anyway, I like the outcome. Also, that's a good use of gradients and tones. It adds depth. :]

Thank's!

These impossible objects are meant to be confusing. It's about taking two regular looking shapes and juxtapozing them seamlessly so the result couldn't came from one simple 3D object as the appearance and details would invoke.

Another usual example is that fork:

You're welcome. :]

*sees fork* You're right. X]
