Now I need to rig two toy keyboards so that they play simultaneous notes.
Up to now, I'm looping wav files and re-recording in a stack...the room acoustics adds some richness to the otherwise bland computer tones. Laborious, not exactly aiding improvisation.

Tea Flakes:

A sugar cube is only a little better than a sugar sphere; only a small amount of surface is exposed to my tea. A sugar snowflake would be better. A sugar flake the approximate diameter of my teacup would be perfect; it would dissolve as it sank to the bottom, insuring a perfectly sweetened cup without any need to dirty a teaspoon.
The next step, of course, would be to impregnate each Sugar Flake with instant tea. This would result in a slightly larger flake, but once dropped into boiling water, a instant cuppa would result.

...Now thats what I call the 21st Century in action.

Daphnia continues to thrive in its jar. The other aquatic life - the mosquito larvae and so forth have perished. the green algae has settled to the bottom of the jar. Several hundred daphnia swarm in the bottle. I wonder how long they will thrive. The bottle's neck is plugged with a bit of cotton wool, so it is not quite a sealed enviroment; still, they've survived longer then I expected.
Now I wish I had taken several jars full, and sealed a couple off as experiments.

Perhaps replacing the piston on a Stirling Engine with a piezeoelectric pedal would generate useful amount of AC power without the need for any moving parts beyond the Displacer? After all, the pressure cycle can be quite fast in a small engine...easily 10 hz and probably could be even better.

In order to hold the index cards, a sort of clipboard style clamp is needed. Now, because a index card is much stiffer than a sheet of paper, this makes flipping through them much harder. What I need is a series of little clamps, each to hold a single index card, and all of them hinged to page rapidly through the deck.

What I need is a notebook crossed with an index card holder.
An index card wallet, if you will.

Of course, a sexual feature should display dimorphism...
