Hi there, I am kinda 4fun miner and I used to mine BTC with one of older cgminer releases. I used it because it has a dynamic intensity, an option which let me mine with desktop fully functioning and I mine when surfing internet or writing. I am looking for new miner with dynamic intensity and new cryptocurrency because mining btc on PC is history. I tried 'scrypt' coins but cgminer's dynamic intensity is not compatible with them.
What mining software with dynamic intensity do you know?
What coins can I mine with it? I prefer pool mining.

Edit: I dont looking for great profits. I just want to mine some alternative currency.
