new to LUA but i made some things:
MirrMix - (my personal favourite) it blends the texture with its mirrowed image, very useful to loop images
it has 4 Mix modes (clip, opacity, texturized clip, texturized opacity)
and 3 mirror blend modes (average, darken, lighten)
StripesInc - generates stripes from a series of row-per-row increments
Zoom&Stretch - Zooms and Stretch the texture
