IOIO-2025: Task-6 (Shark)

Shark

Designed by Tu Kaiming (CHINA)

Difficulty: ******_ _ _ _

Paper size: 35-35 cm

Paper: 30-40 g/m²

Round: 2

this is my favourite model of this olympiad so far!

I enjoyed the folding sequence an I like the outcome of this rather simple model a lot!

@Tu Kaiming did a great job here!

This is my first time judging, but not a single participant executed this model correctly; everyone made the same mistake. Guess what it was? :)

The extra color-changed region behind the pectoral fins?

I′m guessing it could be the colour-changed region on the belly because it is not on the reference model. But that thing is definitely there on the diagram

Absolutely right. This triangle is very easy to hide. I′ve seen many wonderfully shaped designs here; for many, this would be no problem at all. I′m surprised no one thought to do this, even though this detail is clearly visible and shown in the final model image. Well, everyone′s on equal terms. :)

@DimonC1 :

how would you know?

Well, there are rumors... :)

Simone, I am a IOIO team member and judge of all Olympiads, except for 2011 and 2015, in which I participated and was the winner. :)
