Bumble Inc.'s booth engagement project Intro Having a London office with lots of local colleagues and many more visiting from Barcelona, Droidcon London is always a fantastic opportunity for us at Bumble to meet the Android developer community as well as each other: Bumble Tech team at Droidcon London 2023 We usually have a booth presence too. Instead of coding challenges we did in the past, this year we tried something new -- We brought a big screen that attracted quite a crowd: Bumble booth at Droidcon London 2023 We were running a collaborative message board, live mosaics, and lots of custom animations we made using Appyx and Compose Multiplatform on the screen: Collaborative message wall Both to showcase our own in-house technologies and to have a lot of fun -- and indeed we had lots making this happen! But what is this project really about? Project & backing technologies We brought an open-source project backed by our own in house library, Appyx, running on Compose Multiplatform. Since it's multiplatform, it works on your mobile device too of course -- but it just looks gorgeous when launched on desktop, big screen, live! You can check out the project here: GitHub - bumble-tech/live-mosaic: Collaborative message board and dynamic image mosaic for #dcldn23 A collaborative message wall Our goal was to provide an engagement point with the crowd about our technologies in a fun, but low entry barrier way -- we created a collaborative message wall you could add entries to: We supported three types of entries: Text, Image, and even CustomComposable to unlock all your creative potential! All you needed to do was to add your entry to a list in a pull request, and if we merged it it would be featured on our screen live: Starfield As a default, we showed the entries in the "Starfield" visualisation shown above. Later we also enabled this other beautiful showcasing of the entries: Stack of messagesLive mosaic and raffle Every entry added to the message wall also automatically
