PROMULTIS & THE NATION GALLERY

Customer Requirements

The National Gallery required the development of an interactive application that enabled visitors to securely make donations to the Gallery.

  • The application also needed to incorporate functionality for visitors to capture a photograph, which would then be algorithmically merged with a Gallery painting and displayed on a screen in a dynamic mosaic format.

  • Additionally, the application had to include an email feature, allowing users to send the final, personalized image to their inbox.

  • The objective was to deliver a seamless, user-friendly interface that integrated secure payment processing with an engaging, immersive experience, allowing visitors to interact with the Gallery’s artwork in a creative and personalized way.

Promultis Solution


Promultis supplied an 86″ Lightning Screen and a 55" Totem Focus with POS terminal. An interactive presentation was developed for the Totem using graphic assets supplied by the Deadgood Agency.


  • The first part of the application implemented a Worldpay integrated secure payment process in conjunction with the POS terminal fixed to the Totem.

  • The visitor could select one of three payment amounts then pay by credit/debit card and, if requested, receive a printed receipt.

  • The second stage of the application utilises the Totem web camera and allows the visitor to take a series of pictures of themselves.

  • The photographs are displayed on the screen and the visitor is requested to select one image. The selected photograph is then sent to the mosaic application on the 86″ Lightning Screen.

  • The visitor is then offered the opportunity to send the selected image to their email.

  • The Mosaic Software was developed to retrieve the photograph taken on the Totem and merge the photograph into an image of one of the Gallery pictures.

  • The visitor can see the image scroll onto the page then scale and animate into the mosaic. The software judges the best fit for the image against the background painting. The picture builds up on the screen as photographs are added.
