text: Yo, check it out, I'm 'bout to drop some knowledge
  'Bout the skins of plants and animals, they be so polished
  Microscale surface features, intricate and fly
  Giving rise to properties, you won't deny
  
  Water repellency, yeah, it's so directed
  Adhesion, camouflage, and fouling, they're protected
  But hold up, we've been limited, our hands are tied
  Top-down fabrication ain't got the stride
  
  But now, listen up, we got a new technique
  For manufacturing microstructures, so unique
  We use strain-engineered growth of carbon nanotubes
  Aligned and freeform, no need for clues
  
  Offset patterning, that's the key, my friend
  Modulate the growth rate, let the magic transcend
  CNTs collectively bend, during their growth
  Uniformity over large areas, let me take an oath
  
  Curved CNT microstructures, the final shape
  Designed with finite element modeling, no escape
  Compound catalyst shapes, we got multidirectional curves
  Self-organized patterns, man, it really deserves
  
  Conformal coating, that's the ace up our sleeve
  Tuning mechanical properties, believe
  Independent from microstructure geometry, it's true
  Design and manufacturing, complex surfaces, we do
  
  So, there you have it, a rap about this science
  Microscale wonders, breaking the reliance
  On limited processes, now we're on a new path
  With strain-engineered growth, we're leaving a dope aftermath!
