Bubble Projection

The user creates an invisible sensor within sight. A creature that can see invisible creatures, such as with Truesight, can see this sensor. This is the source of the projection. Then the user creates a magic bubble that displays what the sensor sees upon its surface. The bubble is between 1 to 10 feet wide, caster decides. As a bonus action, you can move the bubble up to 15 ft.

Also as part of the spell, you may set a password so that one who has this spell or the Attune Bubble cantrip may tune into your projection.
