### It’s like a grapefruit.

What is the (alleged) connection between the creature in (1) and the strange-looking pattern in (2)?

Clue: We’ve been here before.

Cracked by: BiGFooT , shivathilak , Sandesh , varuns88 , Tathagata Chatterjee , priyananda , yaksha and pratap.

Answer: 1) The conus textile
2) A Rule 30 cellular automata

There is a claim that the pigments on the surface of the Conus’s shell interact with each other exactly as the adjacent elements of the Rule 30 Cellular Automaton do.

 1 : Textile Cone Shell 2 : The tile triangle as generated by Rule 107 Wolfram proposes that 1 is created by the rules of 2 , as per Cellular Automata theory.

3. Dibyo                                Sierpinki’s Gasket as a modification of Pascal’s Triangle.

 1) Textile cone shell. 2) its an intricate triangular pattern found on these shells. the connect is “God, Stephen Wolfram, and Everything Else” where he explains his theory of cellular automata and uses the cone shell as an example in explaining it.

5. Sandesh
 Pic 1: Is some kind of molluscs. Pic 2: Sierpinski\’s Triangles connection is CA-Cellular Automata, a theory propounded by Stephen Wolfram(guy in the clue). Actual connection: Sierpinski\’s Triangles are built based on neighboring triangles\’ numbers and positions. Wolfram\’s theory is that nature also follows theory of CA and the triangles on molluscs are also dependent on neighboring triangles…

 Fibonacci??

7. varuns88       1.Conus Textile 2.Wolfram’s Rule 30 – used as a random number generator in Mathematica. Coonect -> A pattern resembling 2 appears on 1’s shell..

8. varuns88       oops..i meant Connect..

9. Ajay Parasuram   Would you guys mind resetting the scores ?

 The texture pattern of the mollusk can be predicted by a cellular automata, using the Principle of Computational Equivalence, as told by Stephen Wolfram in A New Kind of Science. Or some such nonsense.

12. yaksha   rule 30 mathematica . a simple rule which can produce complex structures in nature.
