A set of Octolively panels can be misaligned by about 10 degrees per connection, to fit along a curved surface. If a steeper curve is needed, you can use a ribbon cable (or individual wires) to connect them together. If you know in advance of building them exactly what configuration you will need, that can enable the use of more compact flexible connections.
One of the default eight programs does have the LEDs normally lit, and then dimming when a hand moves over. It is also possible to reprogram them to modify this or the other programs as you see fit.
