Big horizontal seven segment display

I made this display for a puzzle: a logic maze, which involves adding nand subtracting numbers from a value when moving through the maze and ton be able to see this value I needed a display, which can be seen from neverywhere inside the maze.

The segments needed to be 3 blocks nwide so it can be seen properly, but that gives the disadvantage that nthere are hole between all the junction of segments. So I made a nmechanism which will only push out this block when two neighbouring nsegments are "high" And I also added a block within every corner so it nwould look smoother.

Only if you want to change the number, you first would need to turn it the previous number off, because otherwise some intermediate blocks will stay pushed-out.

The only thing I dislike about this display is that the line formed when ntwo adjacent vertical segments are "on", the middle of the line is nthinner than the rest on the line, especially with the 0, 1 and 7.

It's also a bit laggy, because it is quit big and I added some wiring so the few intermediate blocks will push-out on the right moment.
