When I saw the tint tube stuff come on the scene earlier this year I thought it may be suitable for my star on my carport as last years attempt wasn't startling. The star is approximately 4m high by 3m wide but the perspective makes things look different as it's flat on my 16 degree angled carport roof and is viewed from 30m away. I used 24 channels driving RGB fairy lights that came from Ray and it produced hotspots that I wasn't expecting but I developed a liking for it rather than the even colouring I was expecting.
