Kinda funny when you think about it.
Yes, funny strange. The technique is a great way to have some interactive graphics fun. It's about trying simple edits to the blend and watching what effect it will have. You can't really anticipate how it will turn out. Fun!

[Tip: to edit the start and end objects in a blend that has hundreds of steps, use ctrl+click to select the end shape in the blend -edit as desired- and then use the tab key to switch the selection to the blend's start object. The technique requires many steps in the blend and very high levels of transparency in the start and end objects. Those objects can be lines or shapes. In the case of lines you have line weights, rotations, skewings, scalings, colour, strokes, as well as transparency settings to play with. Lots of variables for something created with as little as two lines.]
