Does anyone know BBC Basic?

[Enflamable]

Hi, yeah so i've just started learning BBC Basic in my computing A level and we got some homework that i cant do at all.

This is gonna sounds childish so brace yourself.

I have to make a animated Christmas card. Doesn't have to be anything big, could just be stars flashing white and black on a black background to resemble snow.

I'm not asking you to do it for me (although that would be much appreciated and i would be forever in your debt) but just some tips as to how i would do this?

I did start it and this is what i go so far, lol.
