Hi,
I need to shrink my project...
I'm using an Arduino Mega 2560 and it's size is too big for what I need.
I heard about the ATtiny 
which ATtiny can I use for ShiftPWM?
What are the requirements for ShiftPWM to run
Or which other method do you recommend?
Can you also give me some tips on how to power many LEDs?
I know that you are selling powerful LED drivers but if it's in my budget and if it would be worth it to buy and works just fine for me, I would buy yours! 
More details:
My team will be performing something and we will be using LEDs.
Some effects to fade in and fade out, perhaps in some props we will need RGB leds.
I've bought 4 single coloured led strips, (600 leds in each strip - red, green, blue and white)
I've also bought 1 RGB led strip, 300 leds in that strip
I bought few EL wires of different colours (they need AC current)
The idea is to use the blue led strip one of the props, (just switch on)
one guy to use the red led strip and EL wire(use one ATtiny to run ShiftPWM? with shift registers?)
the other guy to use the green led strip or RGB led strip and EL wire (use one more ATtiny to run ShiftPWM? with shift registers again?)
one more prop will use about 5 leds, just fade in and fade out selected ones in a certain time (use one more ATtiny to run ShiftPWM? with shift registers again?)
So I need some recommendations how to power the LEDs...
I'm still a newbie specifically in this (circuitry) but not very newbie in stuffs like this (creating stuff).
Really grateful of any help that you can provide, I just need some tips to kick start what to do next...
