Insert has symbol # before hex

Hi,

I'm trying to create a color variable using a hex value. I've downloaded a hex value from an RSS feed in string format. I'm struggling converting the string hex into a usable color variable. I've tried a few different attempts but struggle inserting the hash symbol infront of the hex value.

Any thoughts?

Thanks

Dan

Processing Polar Clock Minute Arc.. Just need a second pair of eyes to look at..

I'm trying to recreate polarclock in processing, I've got so it displays the arcs according to the correct time, but I'm trying to make the second arc update in every frame (24 frames a second) instead of just every second (1 frame a second) to create a very smooth animation. I trying to use millis() to do this, but just can't figure it out for the life of me, the specific line of code is on line 42/43.

Any help would be appreciated.

Thanks
Dan
