question: I am planning a local gardening exhibition to showcase my aubergine varieties and need 8 creative display ideas. Please include and highlight more than 2 ideas specifically for interactive displays. The instruction should be between 60 and 80 words long, and ensure to include a postscript with a suggestion for an aubergine-themed giveaway.
answer: 1. Vertical garden tower.  
  2. Color gradient arrangement.  
  3. **Interactive tasting station.**  
  4. Historical aubergine timeline exhibit.  
  5. **Plant-your-own aubergine seed station.**  
  6. Culinary pairing board.  
  7. **DIY recipe card exchange.**  
  8. Artistic aubergine photo booth.
  
  P.S. Consider giving away aubergine-shaped keychains or small packets of aubergine seeds as a themed memento for visitors.
