The Nanoleaf Canvas and Nanoleaf Light panels are two of my favourite smart light kits and they’re both currently over $100 off on Amazon.
The Nanoleaf Canvas are impressive in particular, as not only can they be controlled individually, they can react to being touched to control things like other lights or smart devices and they can also react music playing around you. They can be had for $244 including free delivery (30% off).
Depending on the shape you like, the regular triangular Nanoleaf lights are also $100 off at $244. These are equally as nice, and you can create interesting shapes with them. They also react to music, but don’t have touch capability.
