Intresting scale patterns

I saw a video on you tube explaiing some way you can make you improvising scales sound more intresting. A example was playing 4 notes in a row of the scale pattern then go back to the second note and the next 4 notes of the scale and continue to the end and do it backwards.

Just wondering if anyone else had anymore similir tips?

Thanks

uhh... melodic minor and indian ragas are played differently up and down.

Don't think you understood my question

Could you rephrase it?
