Ideas Generation
The shower is totally the wrong place for me for the same reason that it is good for everyone else - it has no distractions. For me that is just no inspiration. I don't get idas in any one state, my ideas always bounce off seeing things. Usually I'll see something and have crazy idea about it and then realise that it could be used for making a movie. I actually have a policy of whnever I think of an idea I like, writing it down or drawn a mini storyboard of my idea of doing a sketch of the character so I can always come back to it later.
My favourite place to get ideas is actually more of a state. I get brilliant crazy ideas when I'm really tired. I mean like really really super tired like when you've been awake for two days and can't think straight anymore. Being tired, I find, is like being drunk, but with more clarity + memory. You come up with the same crazy shit but you have better control of it.
Production Time
I could make a minute of animation in way less than a day. Maybe not in flash, but in other mediums. I did one fo those freestyle flash battle things a while ago and made 15 seconds in 1 hour, which included coming up with the idea, animating sound and everything. At uni we get a different task every week and I usually spend one day, or a part of it making an animation. The shortest one I made was 20 seconds I think. My favourite of my portal entries is my Alkaline Trio one and I did that over the space of three days though one fo them I didnt actually do anything on it. That's like 3+ mins though.
Like Luis I usually work near to the deadline but it's usually through poor planning/procrastinating, not some kinky fetish. Saying that, i was fucking pumped by the end of the freestyle flash battle, I started slow and my the end I was just furiously scraping it together. Intense.
