I am thinking of a neat project I could do, but it would require around 60 LEDs. Is it possible to do such a thing with a Arduino/Raspberry Pi? Also, these LEDs would have to be the multicolored ones...
Thank you. Would this work with multicoloured LEDs? These for example: https://www.sparkfun.com/products/11120

It could do if you limit yourself to simple combinations of the three primary colours. (ie, each colour is just on or off). This gives a total range of 8 colours (OFF, red, green, blue, yellow, magenta, turquoise and white)
You'd just treat each of the separate primary colours as a separate LED.
For normal control of RGB LEDs you need 3 output pins (one for each of the 3 colors) for each LED - so you'd need 180 pins for 60 RGB LEDs
The above link provides 64 RGB LEDs that can be controlled by a total of 1 wire (well plus power)
