A Nightly Signature Attraction
In a hotel or resort, a musical fountain is not a static landscape feature — it is a recurring nightly show guests gather around.
Shows are scheduled in advance and start automatically at set times. A representative system has 150 units: 75 motor-pumps for water movement and 75 RGB units for light. The poolside becomes a nameable stage guests expect at a fixed hour — "the 9 PM water show."
Programming a three-minute show by hand can take a specialist 2-4 hours to a week and require 1,500-6,000 commands. Arcus does the same work in minutes, with no specialist.

Guest Experience and Brand Differentiation
In a resort most amenities match the competition: a pool, a spa, a restaurant. A signature water-and-light show every night is hard to copy and turns the property into a landmark.
- Social media: guests film and share the show, producing free, geo-tagged promotion every evening.
- Event anchor: the show time anchors terrace bars, dinner seatings and private celebrations.
- Recall: "the hotel with the nightly fountain show" is a one-line positioning guests remember.
The show is not a fixed video; it can change by season, event or brand — which makes it a reason to return.
After-Dark Light Shows
Light moves the show's most dramatic moment into the evening hours.
RGB colour runs by default only after dark; during the day the water moves without colour, and the show earns its full impact at night. For enclosed atriums, lobbies or shaded courtyards there is an indoor override, so colour can also run in daylight.
Water and light are not separate systems — they move together inside the same choreography. See how the light is authored in AI fountain choreography.
A Repertoire Built From Your Own Playlist
The Arcus AI reads any song end to end and composes an anticipatory choreography for it — it is not a sound-reactive system. That lets you turn your hotel's own playlist into a show repertoire.
| Hand programming | Arcus AI | |
| Time per show | 2-4 hours – 1 week | Minutes |
| Commands | 1,500-6,000 (by hand) | Automatic |
| Specialist needed | Yes | No |
- Separate shows for your brand track, an arrival theme or a seasonal song.
- One-off bespoke choreographies for New Year, holidays or private events.
- Every show is validated in a real-physics 3D simulator before it is built.
Quiet Scheduling and Front-Desk Control
Day-to-day operation stays simple for staff. The system plays shows automatically at set times using 10 schedulers, 100 triggers and a forever list — no one has to stand at the pool.
- Phone app: the front desk or duty manager starts, stops or reschedules the show.
- Optional Raspberry Pi gateway: for internet and audio streaming, enabling remote control.
- Safety: backups, a remote kill-switch and ownership transfer protect the property.
If you already have a pool and its pumps can be driven by a VFD, you can add the system without rebuilding it via retrofit.
