I'm sure someone has done this, but I'm thinking about building an LED matrix out of the LED Flexstrips for Halloween next year.
I was thinking about a resolution of say 60 Pixels wide x 48 Pixels high (which would give me 2400 pixels in total) , but that's like 24 Flexstrips at at about $60 per Flexstrips that's $1400.
Any folks done a matrix with LED Flexstrips that can still display text and animations, with fewer Flexstrips?
