OPTO and PGAV Architects joined forces to create a heavily thematic gift store environment for the St. Louis Aquarium. OPTO's tube-and-clamp system from the Classic Collection were put to good functional and aesthetic use, simulating water pipes and faucets on the post wall systems. The wall systems were paired with Classic Collection floor fixtures and Classic Collection round tables. All systems are mobile, modular, and easily rearranged to accommodate new merchandise vignettes as special events emerge and new seasons arrive.
