Micro Center is running a pretty crazy deal right now on the Nanoleaf Aurora Smarter Kit. This is the base kit with 9 panels. They also have 50% off the expansion kits ($29.99 instead of $59.99).
These things look really amazing in person, and are HomeKit compatible and do all kinds of fast paced effects. Cheapest price I've seen them on sale for was $149, and that was only at Fry's if you had a special coupon email code.
YMMV- but I was able to price match at Best Buy for their starter kit that includes the Rhythm module. Obviously that may not work for you but worth a shot.
