Just a bit of fun for the kids (and maybe the odd adult too!). Twenty five different images, one per day counting down to Christmas with a random festive sample played when you click to reveal the day's image.
There's a second version showing sleeps remaining for younger users.
The only issue I couldn't resolve was the calc for sleeps is still getting 28 for today rather than the 25 it should get from substitution, i.e. today 28 Nov shows -3 sleeps, whilst true, I wanted it to stop at 0, however, if I don't release it now...
