+** Basic Philosphy
+
+Simple, Clean, Haptic
+
+You just wanna touch it ! 
+Borrow design metaphors from real life appliances, before the age of touchscreens. (Ironic isn't it ?)
+
+** Ideas
+*** 3d components
+*** specific purpose:
+**** chat?
+- receipt printer ?????????????????????????
+  - how to keep minimal
+  - endless paper ? textured ?
+  - which animations are needed ?
+    - grow "paper" from bottom line-by-line
+- how to animate editing past msgs ?
+**** casette deck front, with disk in/out
+***** ASCII:
+  ```
+  o=blinkenlights
+  O=eject?
+  ___________________________________________________________________
+  |          ---------------------------------------         ooo O  |
+  |_________________________________________________________________|
+  ```
+***** Blinkenlights
+- 1 light per model?
+  - red=error
+  - blue=ready
+  - green=loaded
+  - blinking=busy
+*** "Controls" (Write/Input)
+**** TextInput ?????
+  - full paper seems to noisy visual wise ???
+    - try "light" paper texture ? (if that exists?)

+**** Button Variants
+***** Kippschalter
