The Blade runs apps, which can display graphics. The visible display has a clear border, but is big enough that you can see photos, videos and notifications, and even play a few games. Streaming video apps should come in the future, if you care to watch shows on your glasses.
The Blade will run Alexa and work with voice assistants, but the current prerelease version I'm using doesn't have Alexa yet. I've tried it, though, and it works. Google Assistant support is also planned.
