An Indiegogo crowdfunding campaign for the Witseer ultra short throw projector is now live. You can use the device to throw 1080p images up to 100-in (~254 cm) wide from 45 cm (~17.7-in) away. Plus, the portable gadget has modular add-ons to transform it into an interactive display, boost the sound or provide battery power.https://www.notebookcheck.net/Witseer-modular-ultra-short-throw-projector-is-now-available.701113.0.html
I'm glad someone is thinking about modular, because too many projectors bundle in features like sound people are better off adding, but there's not really any reason to not just support usb-c for these fuctions. The touch add-on is interesting though. If it were brighter, higher res, laser source I'd check it out.
