"So - what is the deal then - I wonder what gores through the mind when ignoring the blendiness [...] unintentionally non-blendy?"

I wonder what GORES through the mind, too, Thor. For example, 1463 a2 and a3. Blendy mind gore. But there are much better examples of blendy mind gore on previous levels. I'll post some links later.

Unintentional non-blendiness happens all the time, Thor. Did you notice that EHO failed to draw legs for the guy wearing a blue jacket in b2? However, she did manage to attach feet to a section of green background. Perhaps this was her attempt at humor.

Sometimes blendiness is in the mind of the beholder. Eva's style and technique are strong. But even when she is paying close attention to the level as a whole, she can be overpowering. Sometimes she is not an asset to the direction of a level. I'll post some links with examples of this paradox later.
