The 4093 is, by far, a wiser choice. 555s often tend to have "glitches" in their output transitions, which cause CMOS counters to count incorrectly. Great circuit, by the way!
I used a 4093 to generate a clock (but a 555 astable would be okay too, I just had a 4093 already on the breadboard) with a 4017 decimal counter; each output of the 4017 was connected to an input of the display, and the last output was also connected to the counter's RST input to avoid having a gap at the end. :)
this is the coolest thing ive ever seen!!!!!

Thank you for the suggestion. Check out the counting LEDs circuit I made. :)
