Smallest size demo or effect

I have seen a few very small filesize demo's on c64. The 256byte kefren bar was cool. What I am looking for is something even smaller. eg 60 bytes or less. any examples

Try the following btw

sei
.lp1 lda $d012
adc #$08
sta $d011
jmp lp1

Mixed split screen display and top/bottom border removal in 12 bytes

beautyful rasterbars in 5 bytes!

Edit: Not a demo but fun to load before each demo possibly (and only 2 Bytes):

i did the five byte thing (and it worked from a BASIC RUN command too!) and Whiteflame got it down to four bytes... i've been meaning to try beating that, just never found the time. =-)

Yeah, but if we get down to the definitive smallest demo the lot of us can forget that "record" and get on with other stuff. =-)

A friend of mine and I had a competition 'back in the days' to write the short logo-swing routine.

Only much, much later I found out that it's not bytesize but rastertime which is important :)

BTW, he won...
