Bubbles is an unusual filter bank effect plugin (AUv3 and Standalone) aimed at experimental sound design. You can use up to 10 band pass filters, represented by bubbles in the UI, with controllable resonance. Each band can have a dedicated delay with feedback. You can spread the cutoff, resonance, delay time, and delay feedback across each band to get very creative effects, from odd-sounding echoes/reverbs to impossible sequences.
