I just think the novelty of these type of displays was up in the 90s, It's time for an upgrayedd. I propose leprechauns flying up and down the river wearing water jet packs, shooting people with their Chicago-style hot dog cannons would be more with the times. What's your idea?

better yet, make a green dye outta algae, so that it actually does something other than look interesting. And knowing how rivers in cities work, it’s polluted enough that algae will die off withing a few days tops, so it’d be efficient

TL;DR: Algae would almost certainly be worse than whatever they are using.

Great Lakes: Harmful Algal Blooms

Blooms of the blue-green algae, or cyanobacteria blooms, is a frequent occurence in the Great Lakes (particularly in Lake Erie), causing impacts to human and ecosystem health, including fish kills and discolored or foul-smelling water. NOAA provides forecasts of cyanobacteria blooms for Lake Erie from July to October. Some cyanobacteria blooms can grow rapidly and produce toxins that cause harm to animal life and humans so scientists describe them as harmful algal blooms (HABs).
