You can let your message or artwork shine on­ literally with the T-Sketch tee from trade site Thumbs Up.

The "ingenious" new T-sketch features new tech that means whatever you write or draw on it will be converted into an
illuminated message or design.

So, anything drawn on the wipe-clean panel activates a glowing light beneath so that it lights up.

The flashing sequence can be changed to suit your preference­ from a gentle glow right through to a pulsing strobe, presumably to be based on how urgent your message is.

Available in both kids and adult sizes, the tee is powered by two AAA batteries and will be available in orders of 12 or more for £30 each from the end of April.
