This is a good piece of symmetry art by 9-year-old Braden White
BUT... is it a tessellation?
Put your
mouse cursor on the green box below to see
Webmaster Sethness's opinion.
The basic shape repeats perfectly.
If this were just empty triangle shapes, it would be an OK and slightly boring
abstract tessellation.
However, if the picture above is a picture of Yoda, the answer is emphatically
"NO, that is not a tessellation" because the blue triangles are air or space.
Those are GAPS.
After Webmaster Sethness explained this to Braden,
Braden changed those gaps into 1950s-style spaceships.
Now, it's a perfect example of tessellation! Take a look at Braden's new version, below.
