The Transparent Toaster looks great and would be useful to avoid surprises:
A shame it does not toast (yet):
This transparent toaster allows you to see the bread while it is toasting so you never surprised by toast that comes out too dark. This idea is based on the transparent heating glass featured in this issue. Although the glass does not currently get hot enough to toast bread, some day this application may be possible. The concept was developed by the Inventables Concept Studio.
