How to make a wandering dot in SSC?

Hey folks, I've been trying to do that dot, but I just don't... ¬¬
The SSC is still some kinda of mistery for me, so if you could do a wandering dot for me, with random directions, and after, explain how and why, I'd be grateful!!!

that's it, thanks in advance!

Is this what you mean?
Your description is really vague

Yes, but something with less "hard turns", also something that could go throuht all the screen, randomly, but not that much...

Then try altering the values..
Scopes don't get much easier than the one I just gave you.

hint: start (in x and y) with changing cos(tx2) to cos(tx2)*.25 and sin(ty2) to sin(ty2)*.25

thanks man!

I think it will take some time until I learn how to use the SSC.. =/
So many ideas in my mind...
