Rotating text messages on Screen Saver for disabled person?

Question

I have an iMac set up in my mum's living room, she has dementia and I use the computer to speak to her using Facetime and Skype.
I would like to be able to place rotating messages on the screensaver (in large font) to remind her of things e.g. when her shopping is due, with my phone number. I assume this is not possible with OS X, but is there an application that will allow me to do this i.e. rotating messages on screen saver with control of font size?
Thanks in advance

There's no completely simple way to do this but there's one way I can think of that doesn't require advanced geeking:
1. Set up a cloud service such as Dropbox or Google Drive so it runs on her computer and on your computer.
2. On her computer, set the screen saver to use PICTURES from a specific folder only, with whatever effect you like. Choose a folder that's inside the Dropbox or whatever that you set up.
3. Now you can create pictures yourself and put them inside that folder and know that they'll display on your Mum's screen saver. You can choose whatever font and colours and whatever that you want to use for each message.
43 Just make sure that you delete messages once you don't need them anymore, and that that folder only ever has one picture in it - less confusing. You'll probably want a default picture to put in there when there are no other messages, I'm not sure what would happen if the screen saver points to an empty folder.
This isn't the only way to solve the problem but it's probably the simplest.
