Cubic numbers
Create a triangle from the sequence of odd numbers s[n]=2n-1 by writing s[1] on the first row, s[2] and s[3] on the second row, the next three numbers from the sequence on the third row, ... the next k numbers on the k-th row. For example:

(Raumpatrouille – Die phantastischen Abenteuer des Raumschiffes Orion, colloquially aka Raumpatrouille Orion was the first German science fiction television series. Its seven episodes were broadcast by ARD beginning September 17, 1966. The series has since acquired cult status in Germany. Broadcast six years before Star Trek first aired in West Germany (in 1972), it became a huge success.)
