Howdy! Do you remember the time before HD, amoled etc. super sharp screens? When pixels were so big that you could easily count them and any colors were luxury? This is your ticket back to these good ol' times: LedScreen Qt5 & QtQuick 2.0 component! Here is a video presenting it with example applications: This component allows you to use any QML content as the source for the ledscreen, define led size and color or use colors from the source item. So it doesn't contain kitchen sink yet, but there's only so much you can fit into 60 lines of QML + GLSL with API documentation.. ;-) Feel free to grab sources from here & modify & use as you want! PS: Hoping to be able to develop & demo Qt5 soon on Raspberry Pi!
