<div class="text">
<span class="title">The best</span>
The offspring of a customized orbiter, O飇ostem arose as the best balanced
home for our plans. So we submitted to its conditions.
</div>
</div>
<div class="slide">
<img class="diapo" src="images/sf14.jpg" alt="">
<div class="text">
<span class="title">Prototype</span>
O飇ostem's deep impulse flow is selectively regulated by a molecule
originated in the prototype model, that creates its own variational
principles, as oriented by the first local generation of terminable androids.

<div class="slide">
<img class="diapo" src="images/sf24.jpg" alt="">
<div class="text">
<span class="title">Has been reduced</span>
Paired hosts come out nicely after only two cycles now. Their size has been
reduced to a half the original as planned, and indeed they show an
evolutionary advantage in the process of fixing self-generated instructions.
Plus, they are beautiful.
</div>
</div>
<div class="slide">
<img class="diapo" src="images/sf04.jpg" alt="">
<div class="text">
<span class="title">By close-alikes</span>
Now I have regained hopes in someday finding myself surrounded by
close-alikes to us. However, they will not be audible, at least not in my
life span. We resolved the low freq vibration a superior solution for our
communicational goals ...
</div>
</div>
<div class="slide">
<img class="diapo" src="images/sf01.jpg" alt="">
<div class="text">
<span class="title">To bear</span>
We did not expect their surface to produce such a carbon powder coat, though
this is the best model so far. I shall have to bear with the inconveniences.
They seem to establish a parallel communication through that carbon coat and
I find myself unable to decodify the signal into anything meaningful.
</div>
</div>
<div class="slide">
<img class="diapo" src="images/sf15.jpg" alt="">
<div class="text">
<span class="title">The zero level</span>
Today a set of vibration came up from the zero level; we expect to launch
the transitional program in no longer than five basetime units. Psykesoma? galore and we'll betray our very nature into infinite, unending 2D surfaces.
We do need that vibration, and we will conquer its source.
</div>
</div>
<div class="slide">
<img class="diapo" src="images/sf41.jpg" alt="">
<div class="text">
<span class="title">Beautifully</span>
To keep my sanity I wear the tactile sensors all the time. They translate
beautifully; I can even see distances while still on Psykesoma. This was
quite a discovery. We have grown more adaptable than expected.
</div>
</div>
<div class="slide">
<img class="diapo" src="images/sf26.jpg" alt="">
<div class="text">
<span class="title">Uneasy to match</span>
Yewoona had to travel farther and longer than I did. Her base orbiter was
set to keep a complex combinational path that made it uneasy to match our
circuits. But her nature showed stronger than programmed.
</div>
</div>
<div class="slide">
<img class="diapo" src="images/sf50.jpg" alt="">
<div class="text">
<span class="title">Adapted to serve</span>
Keep feeding them. We will never be this lucky again; an autogenerated
species adapted to serve all our needs!
</div>
</div>
<div class="slide">
<img class="diapo" src="images/sf19.jpg" alt="">
<div class="text">
<a class="title" href="http://www.dhteumeuleu.com">At soonest</a>
"Blood is dark red, iron dark blue, this tale is blissful and so are you". I
should get to the hotel at soonest. The agency guy must be there already,
with some luck we'll have some nice dinner on him. How's that?
