So, i found a way to generate gif's via php, so i did script, that makes dynamic signatures in fallout 1-2 style.

It lags as hell on first load, but then caches and loads much faster(but still it's about 1mb file to load).
Please, dont use it as dynamic signature - my host will crush because of overload. Just save .gif and rehost it somewhere.
And... if you know any fast free hosting, that would not ban me because of overloading scripts - pm me it's name.
