Henry Ortega from Iglesia la Fraternidad in Quito, Ecuador brings us this livestream setup.
They used two LED strip lights for backlight. Then they put black drapes all over the wall.
The panels at the back were DIY. They are squared wooden frames that they painted black. And in the inside they used RGB LED strip lights. And they covered the panels with plastic film.
Finally, they put a TV in front of it as a teaching monitor.
