Blocks, Vilnius Light Festival 2025
Twelve blocks down.
This is the real wall: Blocks, on a school in Vilnius.
Nine games at once, about 80 people in the queue, each playing from their own phone. I build these for festivals, launches, stands and conferences.

You knocked out the whole name.
As compensation for your procrastination, I’m giving you 20% off your first project.
I build games your crowd plays on a building or a screen, from their own phones. No app. For festivals, launches, stands and conferences. 12 blocks, then the real wall.
Creative developer and interactive artist, Vilnius
Paulius Šaparnis. I turn watchers into players in ten seconds.
Playable installations for festivals, cities and brands: facades, LED screens and big TVs that crowds play from their own phones.
Vilnius Light Festival 2025 and 2026. Blocks has been invited to Llum BCN, Barcelona, February 2027.
Played on buildings
Two winters at Vilnius Light Festival, two interactive facade games on buildings that were never meant to be screens. All work
Ping Pong
Vilnius Light Festival, 2026. With Aleksandr Voronovič
Three courts on the Contemporary Art Centre. Visitors played in pairs, phone against phone.

Played from their own phones
A QR code near the building opens the game in the phone’s browser. No app, no download. Visitors join a live queue, and when their turn comes the phone is the controller and the building is the screen.
Festival pieces like these: from about €5,000. About six weeks from go-ahead to opening. For a launch, a stand or a conference, every project is priced individually. Where should it play?
Not just facades
The same approach works as a light or sound object, and on LED screens and big TVs. Light and sound are on film here, screens in photos.
Light objects
Animated Glowing Stained Glass. Panevėžys Wedding Palace and Culture Palace, 2024
Light for existing architecture: stained glass in two Panevėžys buildings, animated with light after dark. The glass is by Kazys Morkūnas and G. L. Baginskienė; my part is the light. I also build objects that glow and respond to the people around them.

Bus Synthesizer. Panevėžys bus depot, 2022. With the creativity centre Pragiedruliai
Instruments to touch and turn. A retired bus brought back as an instrument: visitors played it by touching the handrails. Or a pipe with knobs.

LED screens and big TVs
Live message wall at band concerts. Stages, stands, lobbies and launches
The audience scans the code on the stage, writes on their own phones, and the messages appear on the screen during the concert. A big TV in a lobby or on a stand works the same way.
450 messages sent to an LED screen in 15 minutes, at a band concert (approx.)
Can it run on your screen? Usually yes. Send me the screen’s size and resolution, and I will tell you what fits.

Where should it play?
Pick the nearest. It is noted on the form, and a name and an email are enough to send. From a few lines I work out an idea and a price.

A light festival
The building becomes the screen. At Blocks, about 80 people queued for 20–30 minutes to play.
From about €5,000. About six weeks from go-ahead to opening.
-
A city square or a building
A new work for your site, or an earlier one adapted to it. I start from your building: its grid, its size and where the crowd will stand.
From about €5,000. About six weeks from go-ahead to opening.

A product launch
A game in your brand’s style on your LED screen, big TV or projection. Guests scan a QR code and play from their own phones. No app.
Every project is priced individually. Allow a few weeks; I confirm the timeline with the quote.
-
A stand at an exhibition or trade show
Guests play instead of walking past, on a big TV or the stand’s LED screen. Joining can double as a sign-up, always with consent.
Every project is priced individually. Allow a few weeks; I confirm the timeline with the quote.

A conference, a company event or a party
The stage screen becomes a game or a live message wall. At a band concert the audience sent about 450 messages to the LED screen in 15 minutes.
Every project is priced individually. Allow a few weeks; I confirm the timeline with the quote.

Something else
Not sure where it fits? A short meeting is enough to work out what your audience could play, and where.
