@mike_g:
i think the question isn't so hard, because both exes are different... so you alone must know what you want to do and how your intro should look like.... should it look more like version1 or version2? The balls in version2 looks like a clearscreen is missing, because all balls will drawn on screen without removing.... in version1 seems to be an added clearscreen, because drawed balls will be deleted on old pos which looks more nice for me as version2...
At least, i think you should know what you want to code... how your intro should look like and what source is more readable / complete for you ^^ Just my opinion...
[edit]
possible you should create a 3rd version (new version) and copy/paste routines from the old two versions into the new one ^^ good luck
