Navigating by the Sun

I was messing about while building a floor on my boat and got distracted by a sunbeam (because I am very easily distracted) and started wondering how much information could be determined by this pattern of sunlight. [more inside]

How to Get More Light?

I recently moved into a new apartment on short notice. One thing I didn't realize when kicking the tires was that there is no natural light in my bedroom during the morning. This tends to make waking up an unpleasant and lengthy event—it's dark, and often I just fall asleep again. I don't want this to happen, and I've noticed that when I sleep in a room with good morning light exposure I wake up earlier and happier. So: how can I replicate a rising sun in my room? Full spectrum light (like for SAD) hooked up to a dimmer hooked up to a timer? Clever arrangements of mirrors?

Software which provides 3D sunlight modelling for various house designs.

I am designing a house and using the wonderful suncalc.net/ I have been able to view the daily path of the sun throughout the year, for a given set of co-ordinates. I would however like to go one step further and model how different 3D house shapes would fare for sunlight throughout the year at a specific place on the surface of the earth. I am willing to pay for this software if necessary.

How to get the sunlight into my cube?

We've been told for some time at work that we're going to be moved from a second floor, windowless area down to the first floor which is at street level and has floor to ceiling windows looking out at street level. This sounds great! However, I just saw the plans and it appears that the cubicles which we have the option to choose from all have cube-height (six foot?) walls between our chairs and the windows. Think back to Office Space. [more inside]

Fever at night, but morning's alright

When I'm battling an infection/virus for a few days, my body temperature climbs as the sun goes down. My village elders tell me this is normal. Why do fevers get worse after sundown, but subside in the morning?

art and sunlight damage

I have a pencil (maybe charcoal?) sketch of Pompeii my mom drew, about 50 years ago. It's gorgeous. It's been tucked away because I'm afraid of light damaging the picture. Are there any specialty picture frames/glass coverings I can use to display her artwork, while minimizing fading or light damage?
