3-tier graduation cake with Purdue, rock climbing, and Rice/Medtronic themes.

Design a 3-tier celebration cake, each layer representing a different theme in a cohesive and creative way. Bottom Layer (Purdue University Theme): Use black and gold as the primary colors. Decorate with the Purdue "P" logo, gold gears, and train track elements to symbolize Purdue's engineering and Boilermaker heritage. Optionally include the Purdue Bell Tower or Purdue Pete in fondant. Keep the design clean and collegiate with a matte black finish and gold accents. Middle Layer (Rock Climbing / Workout Theme): Incorporate earth tones like gray, brown, and green, with pops of neon (like gym gear). Make the sides look like a textured rock climbing wall with fondant climbing holds scattered across it. Add mini climber figures on ropes ascending the cake, and include small gym items like a kettlebell, yoga mat, or dumbbell in fondant. This layer should feel dynamic and rugged. Top Layer (Rice University + Medtronic Theme): Use navy blue and Medtronic blue/white as the color scheme. Decorate one side with the Rice "R" crest and the other with the Medtronic logo. Add a tiny fondant white coat, stethoscope, and optionally a miniature medical device like a pacemaker. Place a graduation cap or diploma scroll on top, or a fondant figure in a lab coat. Additional Elements: Add a staircase or rope design connecting the tiers to symbolize personal and professional growth. Use LED tea lights or metallic dust for accent lighting. Optionally, wrap a timeline around the layers with text: See more
