Hypothesis: I can hand-draw a stereogram!

Conclusion: You tell me! Can you see it 3d?

#stereogram

@noneuclideandreamer the last one is hard, perhaps some clues on the outside could help the eyes align.
@shironeko I mean the angle of the last one is so that you basically only see one face...
@noneuclideandreamer yeah so my eyes naturally want to align the front face but that's slighty too far apart for stereo.

@shironeko Hmm, that of course highly depends on the size of your screen...

My little squares are 0.5cm. I assumed for my calculations an eye distance of 8cm and a eye-screen distance of 32cm. But intererestingly it seems to kinda work for different zoom factors.
