Digital Rain - Who wants to help me make this even cooler?

I know this should probably be in the watercooler section but there's rarely ever anyone on there to read your posts and I know some of you guys will probably find this fun and want to help

I've taken this very cool matrix 'digital rain' effect from the below link. It uses conditional formatting and a scroll bar to make it work. I've changed it up a bit. attached. changed the conditional formatting to add more colours. I also got rid of the scroll bar and created a macro to increase the value in A1(hidden) as time passes. In my workbook this sheet is veryhidden and gets activated after the user finds a wee button and goes through some matrix lines in the form of prompt boxes. and the timer gets set off when the page becomes actived.

It looks cools, but I'd like some ideas of how to make it cooler. I've been thinking we could add some code so when the numbers reach a certain cell that cell will change to a letter and eventually a word will be spelled out. Other suggestions are welcome.

The little box to run the macro is at the right hand side between the two sets of hyperlinks. I've deleted the other pages from this workbook because it's an actual spreadsheet I use at work that I've built this into as a sort of easter egg.

Many thanks to anyone who wants to join in with this
