The technology makes it possible for optical illusions to be projected into the night sky, capturing the attention of passersby like no other. The persistence of vision is an optical illusion that happens when visual perception of an object does not stop after the rays of light from it have ceased to enter the eye. Based on this effect, Echo is able to "print" a vertical series of light before the eyes of the viewer to create a complete image. Over the course of three days, [Marriott Hotels has been projecting images](https://www.trendhunter.com/trends/marriott-bonvoy-x-mercedes) over the Thames of Paris' iconic Eiffel Tower and the Colosseum in Rome as an extension of its Travel Brilliantly campaign. ## Trend Insights (Trend Hunter) - Score: 2.0/10 - Popularity: 15% | Activity: 37% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Marketing](https://www.trendhunter.com/marketing) > [Billboards](https://www.trendhunter.com/billboards) ## Key Themes ### Why This Trend Is Growing - **Echo Projection Technology:** The innovative Echo projection technology from Lightvert allows for optical illusions to be projected into the night sky, creating captivating visual experiences. - **Persistence of Vision:** The persistence of vision, an optical illusion, forms the basis for Echo's ability to 'print' a vertical series of light and create complete images. - **Travel Brilliantly Campaign:** Marriott Hotels' Travel Brilliantly campaign leverages Echo projection technology to captivate passersby with projected images over famous landmarks, providing a unique and immersive brand experience. ### Industries Being Reshaped - **Hospitality:** The hospitality industry can benefit from Echo projection technology by enhancing guest experiences through captivating visual displays in hotel properties. - **Advertising:** The advertising industry can explore the use of Echo projection technology to create disruptive and attention-grabbing outdoor campaigns that engage viewers in novel ways. - **Event Management:** Event management professionals can incorporate Echo projection technology to transform venues with visually stunning displays, adding a unique and memorable element to events. ## Related on Trend Hunter - [Futuristic Immersive Lighting Experiences](https://www.trendhunter.com/trends/immersive-lighting-experience.md) - [Immersive Lighting Installations](https://www.trendhunter.com/trends/immersive-lighting-installation.md) - [Cinematic Travel Campaigns](https://www.trendhunter.com/trends/cinematic-travel-campaign.md) - [Branded Digital Light Shows](https://www.trendhunter.com/trends/maybank-light-show.md) - [Spooky Street Ad Experiences](https://www.trendhunter.com/trends/fanta-halloween-projection.md) - [Projector Brand-Supported Events](https://www.trendhunter.com/trends/cirque-du-soleils.md) - [Immersive Hotel Art Installations](https://www.trendhunter.com/trends/hotel-art-installation.md) - [Gamified Hotel Campaigns](https://www.trendhunter.com/trends/moxy-universe-play-beyond.md) - [Immersive Digital Art Galleries](https://www.trendhunter.com/trends/the-reel-store.md)
