I'm using 2 MAX7221 chips, they work great. Apart from that also 5mm high brightness leds, but just using 2 MAX7221s, they don't dim that much... just have to figure out a better solution...

It was hard to find a suitable large stripboard but I got it from here http://uk.farnell.com/vero/01-0042/veroboard-179-07x454-66mm/dp/1536942?Ntt=stripboard enough to make 2x clock (that I did)

The led looks a bit focused. Did you get the diffuse LEDs or not? Diffuse leds can be viewed from a large range of angles. Their plastic housings look rougher than a smooth plastic surface.

If this question is directed at me then no I did not use diffused LED's. I used these http://uk.mouser.com/ProductDetail/Cree-Inc/C535A-WJN-CS0V0151/?qs=%2fha2pyFadugYYN%2fkEaGd5KoOjGvMC7QxGs05ryBegjRuYV232%2fuYlWKl%252b6XNvG2l to get the desired light cone diameter 1.6mm-2mm above the lens.
