Was messing around with expressions and controls last night, and I came up with this responsive grid setup in #AfterEffects
Here's the free project file if you want to try it out!

[After Effects] Here's an expression to get the current date and format it mm/dd/yy.
If you don't need it specifically, remember AE now uses the V8 Javascript Engine so you can use things like Date() natively - has a ton of applications!
