Thank you !

Don't know of any commercial IC's. You can cascade 2 4-bit counters.

EDIT: 74LS592. It was designed after I stopped doing design professionally. I wouldn't design it into a product because they cost $11 each in quantity 100 at Mouser.

 

CD4024?

 

74LS592 is a ripple counter and I wouldn't use it. If you use it, you need to design around any glitches on the outputs.

CD4024 is a dual 7 stage counter.

Just cascade 2 CD4516.

 

I managed to make it work - success !

Post your schematic if you'd like it critiqued.

 

Here it is:
The very short version: ---video--- (watch this first)

Hidef of the final working circuit:

Notes:
No resistors in simulation because they will screw up the results. But put ~300R in reality on both sides of the LED Matrix, to be sure.
