App Sevilla / Cofradías real-time tracking (Semana Santa)
Seville's municipal app added a Holy Week module for 2026 that GPS-tracks each cofradía (hermandad/brotherhood) minute-by-minute from Viernes de Dolores to Domingo de Resurrección, showing the position of the cruz de guía and each paso, plus a public density 'traffic light' powered by 40 city sensors signaling crowding by zone.
Each hermandad is bound to a parish/barrio (Triana, San Lorenzo, Macarena, etc.), and the simultaneous tracking of dozens of cofradías across the same week makes their parallel processions and the inter-barrio identity (e.g, Triana's Esperanza vs. Macarena's Esperanza) legible and comparable.
Hermandad members and parish/barrio communities use the tracker to follow their own paso, plan relay points for costaleros, and coordinate where to join. Supporting the deep intra-hermandad/intra-barrio fraternity that anchors these confraternities year-round.
A municipal-run, year-after-year live deployment around an entirely religious traditional neighborhood institution. Notable for combining live position with a crowd-density layer. A UX pattern that solves the 'too many crews, too few spectators' problem.

Cidade em Jogo (Cities in Play)
Wilson Center + BRAVA Foundation (Brazil) serious game where Brazilian teens become mayor of a city and balance policy goals vs fiscal reality. 35,000+ players, 2,500+ engaged students; 67-69% of players report increased political interest/efficacy after play. Spawned real 'Mayor for a Day' partnerships in cities like Jundiaí, where 3 students presented neighborhood flooding to their actual mayor.
falles.app / Komissió / Mundo Fallas / FallaWallet
Ecosystem of dedicated SaaS platforms for managing Valencian falla commissions (the neighborhood associations that build the Fallas monuments and run festivities). Each comisión gets a branded app for members to pay cuotas, register for events, get QR/NFC wristband event entry, manage the bar/casal tab, see news, etc. Coexist alongside the JCF Ofrenda app to form a hybrid traditional-digital stack.
Notting Hill Carnival Sound Systems
30+ permanent sound systems (Aba Shanti-I, Disya Jeneration since 1985, Killerwatt, Channel One, Rampage, Arts-A-Light, etc.) take over specific street corners across Notting Hill, Westbourne Park, and Ladbroke Grove for the carnival weekend. Each system is a long-running crew with home turf and stylistic identity (roots reggae, ragga, dub, soca, UK garage). The parallel Panorama is the formal UK National Steel Pan Championship between steel-band crews.
Jane's Walk Festival
Every May, residents in 500+ cities lead free, neighborhood-led walking conversations on their own block, route, or theme. Anyone can register a walk. The Academy of Urbanism and other partners run callouts and award recognition to standout walks/cities. Themes range from local history and architecture to homelessness, queer history, and skid-row planning fights.
App Oficial Ofrenda (Junta Central Fallera, Valencia)
Official app from the Junta Central Fallera (governing body of Valencia's Fallas) that tracks all 384 fallera commissions live during the two-day Ofrenda de Flores parade. BLE 5.0 chips are inserted into each commission's banner (estandarte/cruceta) to measure passage times and current location along the two parade routes (San Vicente and La Pau). Users get push notifications when their chosen commission passes checkpoints. Same chip technology is used in Madrid/Barcelona/Seville marathons.
Concurso Decora tu Barrio (Centro León) and Spanish municipal barrio decoration contests
Family of municipally-run annual contests where neighborhoods/barrios (organized via neighborhood associations) compete on Christmas illumination and façade decoration. Categories explicitly include 'parishes/neighborhoods' as a unit (alongside individuals). Most run hybrid digital intake (online registration, social media voting, judging visit scheduling) layered on a centuries-old block-decoration tradition.
