this is my first clock, which makes it cool. I wish your strobes were timed so the second hand fell on the digits. I actually kind of wish there wasn't a 2nd hand at all and just the blurring of the minute hand...that would give it a super, eerie kind of feel for me.
Interesting take on how to do a long exposure! I like what you've done in terms of composing and choosing how to expose, but the clock does look a bit of out focus which is distracting.
Having a little trouble with liking the execution though... the blur on the one hand is good, but the extra flashes are a bit less well done I think... The lighting isn't balanced either, which washes out the black numbers...
The reason that I didn't go with something like this is that it would have been very difficult for me to give it a special context...
