Your panel looks good, very eye-catching! I'd definitely give it a go again, I'm pleased with the results of mine - you could always get one of the multi-colour LED strips with the controller and then change the colours to how you want them. LCD panels do create a very diffuse light but I think this would be difficult to replicate. Maybe someone else would have better luck than me if they tried to light the panel just from the sides! I can't find the link where I saw people experimenting but they used the diffuser film taken from a LCD monitor and it seemed to work well.
